Imidazopyrimidinyl and imidazopyri dinyl derivatives

FIELD OF THE INVENTION

The invention presented herein is directed to novel imidazopyrimidinyl and imidazopyridinyl derivatives, and to their use as CRF antagonists in the treatment of a variety of neurological and psychiatric disorders.

BACKGROUND OF THE INVENTION

Corticotropin releasing factor (herein referred to as CRF), a 41 amino acid peptide, is the primary physiological regulator of proopiomelanocortin (POMC)--derived peptide secretion from the anterior pituitary gland [J. Rivier et al., Proc. Nat. Acad. Sci. (USA) 80:4851 (1983); W. Vale et al., Science 213:1394 (1981)]. In addition to its endocrine role at the pituitary gland, immunohistochemical localization of CRF has demonstrated that the hormone has a broad extrahypothalamic distribution in the central nervous system and produces a wide spectrum of autonomic, electrophysiological and behavioral effects consistent with a neurotransmitter or neuromodulator role in the brain [W. Vale et al., Rec. Prog. Horm. Res. 39:245 (1983); G. F. Koob, Persp. Behav. Med. 2:39 (1985); E. B. De Souza et al., J. Neurosci. 5:3189 (1985)]. There is also evidence that CRF plays a significant role in integrating the response of the immune system to physiological, psychological, and immunological stressors [J. E. Blalock, Physiological Reviews 69:1 (1989); J. E. Morley, Life Sci. 41:527 (1987)].

Clinical data provides evidence that CRF has a role in psychiatric disorders and neurological diseases including depression, anxiety-related disorders and feeding disorders. A role for CRF has also been postulated in the etiology and pathophysiology of Alzheimer's disease, Parkinson's disease, Huntington's disease, progressive supranuclear palsy and amyotrophic lateral sclerosis, as they relate to the dysfunction of CRF neurons in the central nervous system [for review see E. B. De Souza, Hosp. Practice 23:59 (1988)].

In affective disorder, or major depression, the concentration of CRF is significantly increased in the cerebral spinal fluid (CSF) of drug-free individuals [C. B. Nemeroff et al., Science 226:1342 (1984); C. M. Banki et al., Am. J. Psychiatry 144:873 (1987); R.D. France et al., Biol. Psychiatry 28:86 (1988); M. Arato et al., Biol Psychiatry 25:355 (1989)]. Furthermore, the density of CRF receptors is significantly decreased in the frontal cortex of suicide victims, consistent with a hypersecretion of CRF [C. B. Nemeroff et al., Arch. Gen. Psychiatry 45:577 (1988)]. In addition, there is a blunted adrenocorticotropin (ACTH) response to CRF (i.v. administered) observed in depressed patients [P. W. Gold et al., Am J. Psychiatry 141:619 (1984); F. Holsboer et al., Psychoneuroendocrinology 9:147 (1984); P. W. Gold et al., New Eng. J. Med. 314:1129 (1986)]. Preclinical studies in rats and non-human primates provide additional support for the hypothesis that hypersecretion of CRF may be involved in the symptoms seen in human depression [R. M. Sapolsky, Arch. Gen. Psychiatry 46:1047 (1989)]. There is preliminary evidence that tricyclic antidepressants can alter CRF levels and thus modulate the numbers of CRF receptors in the brain [Grigoriadis et al., Neuropsychopharmacology 2:53 (1989)].

Furthermore, CRF has been postulated to have a role in the etiology of anxiety-related disorders, and is known to produce anxiogenic effects in animals. Moreover, interactions between benzodiazepine/non-benzodiazepine anxiolytics and CRF have been demonstrated in a variety of behavioral anxiety models [D. R. Britton et al., Life Sci. 31:363 (1982); C. W. Berridge and A. J. Dunn Regul. Peptides 16:83 (1986)]. Preliminary studies using the putative CRF receptor antagonist .alpha.-helical ovine CRF (9-41) in a variety of behavioral paradigms demonstrate that the antagonist produces "anxiolytic-like" effects that are qualitatively similar to the benzodiazepines [C. W. Berridge and A. J. Dunn Horm. Behav. 21:393 (1987), Brain Research Reviews 15:71 (1990)].

Neurochemical, endocrine and receptor binding studies have all demonstrated interactions between CRF and benzodiazepine anxiolytics, providing further evidence for the involvement of CRF in these disorders. Chlordiazepoxide attenuates the "anxiogenic" effects of CRF in both the conflict test [K. T. Britton et al., Psychopharmacology 86:170 (1985); K. T. Britton et al., Psychopharmacology 94:306 (1988)] and in the acoustic startle test [N. R. Swerdlow et al., Psychopharmacology 88:147 (1986)] in rats. The benzodiazepine receptor antagonist (Ro15-1788), which was without behavioral activity alone in the operant conflict test, reversed the effects of CRF in a dose-dependent manner while the benzodiazepine inverse agonist (FG7142) enhanced the actions of CRF [K. T. Britton et al., Psychopharmacology 94:306 (1988)].

It has been further postulated that CRF has a role in immunological, cardiovascular or heart-related diseases such as hypertension, tachycardia and congestive heart failure, stroke, osteoporosis, premature birth, psychosocial dwarfism, stress-induced fever, ulcer, diarrhea, post-operative ileus and colonic hypersensitivity associated with psychopathological disturbance and stress.

The mechanisms and sites of action through which the standard anxiolytics and antidepressants produce their therapeutic effects remain to be elucidated. It has been hypothesized however, that they are involved in the suppression of the CRF hypersecretion that is observed in these disorders. Of particular interest is that preliminary studies examining the effects of a CRF receptor antagonist (alpha helical CRF9-41) in a variety of behavioral paradigms have demonstrated that the CRF antagonist produces "anxiolytic-like" effects qualitatively similar to the benzodiazepines [for review see G. F. Koob and K. T. Britton, In: Corticotropin-Releasing Factor: Basic and Clinical Studies of a Neuropeptide, E. B. De Souza and C. B. Nemeroff eds., CRC Press p221 (1990)].

Other compounds reported to have activity as corticotropin releasing factors are disclosed in WO 95/33750, WO 95/34563 and WO 95/33727; these compounds also do not have the structures of the compounds provided herein.

DETAILED DESCRIPTION OF THE INVENTION

This invention provides certain compounds, as well as stereoisomers thereof. Accordingly, compounds provided herein can have one or more asymmetric centers or planes, and all chiral (enantiomeric and diastereomeric) and racemic forms of the compounds are included in the present invention. Many geometric isomers of olefins, C.dbd.N double bonds, and the like can also be present in the compounds, and all such stable isomers are contemplated in the present invention. Compounds are isolated in either the racemic form, or in the optically pure form, for example, by resolution of the racemic form.

Pharmaceutically acceptable salts of compounds of this invention are also provided herein. The phrase "pharmaceutically acceptable" is employed to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio. "Pharmaceutically acceptable salts" refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines, or alkali or organic salts of acidic residues such as carboxylic acids. Pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. Such conventional nontoxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, nitric and the like; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, isethionic, and the like.

Pharmaceutically acceptable salt forms of compounds provided herein are synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts are, for example, prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., 1985, p. 1418, the disclosure of which is hereby incorporated by reference.

In the compounds of this invention, "alkyl", means saturated hydrocarbon chains, branched or unbranched, having the specified number of carbon atoms. "Alkenyl" means hydrocarbon chains of either a straight or branched configuration and one or more unsaturated carbon-carbon bonds which may occur in any stable point along the chain, such as ethenyl, propenyl, and the like. "Alkynyl" means hydrocarbon chains of either a straight or branched configuration and one or more triple carbon-carbon bonds which may occur in any stable point along the chain, such as ethynyl, propynyl and the like. "Alkoxy" means an alkyl group of indicated number of carbon atoms attached through an oxygen bridge. "Cycloalkyl" means saturated ring groups, including mono-, bi- or polycyclic ring systems, such as cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, and so forth. "Halo" or "halogen" means fluoro, chloro, bromo, and iodo. "Haloalkyl" means both branched and straight-chain alkyls having the specified number of carbon atoms, substituted with 1 or more halogen. "Haloalkoxy" means an alkoxy group substituted by at least one halogen atom.

"Substituted" means that one or more hydrogen on the designated atom is replaced with a selection from the indicated group, provided that the designated atom's normal valency is not exceeded, and that the substitution results in a stable compound. "Unsubstituted" atoms bear all of the hydrogen atoms dictated by their valency. When a substituent is keto, then 2 hydrogens on the atom are replaced. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds; by "stable compound" or "stable structure" is meant a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent.

Compounds provided herein are of the formula I: ##STR00003## wherein A is N or C--R.sup.7 and B is N or C--R.sup.8, provided that at least one of A and B is N.

The haloalkoxy group is C.sub.1-4 haloalkoxy, preferably --OCHF.sub.2 or --OCF.sub.3, and most preferably, --OCHF.sub.2.

Ring member atoms unoccupied by a haloalkoxy group can be unsubstituted or, optionally, substituted with 1-3 additional moieties; preferably at least one ring member in addition to the atom substituted with haloalkoxy is also substituted. Most preferably, the first of said additional substitutions is on the carbon atom adjacent to the carbon of ring D which is the point by which the ring is attached to the imidazopyridine or imidazopyrimidine ring (e.g., at the 2 position of the phenyl ring wherein ring D is phenyl).

Optionally, Ring D may also have a third substitution, or a second substitution in addition to the haloalkoxy substituent, said additional substitution being at any of the available positions on the ring. Preferably, said additional substitution is on a carbon atom between: (1) the carbon atom to which the haloalkoxy is preferably attached (e.g., the 4 position of the phenyl ring when ring D is phenyl) and, (2) the point of attachment of ring D to the imidazopyridine or imidazopyrimidine rings, and is also preferably further along the ring than is the haloalkoxy substituent (e.g., at the 5 or 6 position of the phenyl ring where ring D is phenyl). More preferably, the additional substitution is also on a carbon atom adjacent to the preferred haloalkoxy location (e.g., at the 5 position of the phenyl ring where ring D is phenyl).

Compounds of formula (I), including, but not limited to, the preferred compounds described hereinabove, are prepared by a number of means well known to ordinarily skilled artisans given the teachings of this invention. These include the following synthetic routes and schemes, readily understood by those of ordinary skill in the art.

For example, compounds of formula (I) are prepared by the reaction shown in Scheme 1. ##STR00010##

A compound of formula (II) is, for example, alkylated on the imidazole nitrogen atom with an appropriate reagent. Typical conditions for this transformation include treatment of compound (II) with a base, such as sodium hydride, potassium tert-butoxide, sodium hexamethyldisilazide, etc., followed by a reagent J--R.sup.1, where J represents a halide (chloride, bromide or iodide) or pseudohalide (tosylate, mesylate, triflate, etc.), at an appropriate temperature (0.degree. C. or room temperature, with warming if necessary) in a solvent such as tetrahydrofuran, dimethylformamide or dimethylsulfoxide. Alternatively, this reaction is performed using the Mitsunobu conditions (Mitsunobu, Synthesis 1981, pp. 1-28). The compound (II) is treated with an alcohol compound R.sup.1OH, along with a phosphine (triphenyl, tributyl, etc.) and a phosphine-activating reagent such as diethyl azodicarboxylate.

Compounds of Formula (II) are, for example, prepared according to the route shown in Scheme 2. ##STR00011## A compound of Formula (III) is coupled to an aromatic compound of Formula (IV), with elimination of the elements of M--K; for compound (III), K represents a halide, pseudohalide (such as mesylate, tosylate or triflate), or thiomethyl, and P represents a protecting group (if the conditions of the reaction warrant protection of the imidazole N--H; otherwise, P can be H). Suitable P groups may include benzyl, 4-methoxybenzyl, methoxymethyl, trimethylsilylethoxymethyl, tert-butoxycarbonyl or benzyloxycarbonyl. For compound (IV), M represents groups such as lithium, bromomagnesium, chlorozinc, (dihydroxy)boron, (dialkoxy)boron, trialkylstannyl and the like. The coupling reaction may be performed in the presence of an appropriate catalyst, such as tetrakis(triphenylphosphine)palladium, bis(triphenylphosphine)palladium dichloride, [1,3-bis(diphenylphosphino)propane]nickel dichloride, etc.

Two particularly useful methods involve the coupling of chloroheterocycles with in-situ-prepared arylzinc reagents according to the method of Negishi et al. (J. Org. Chem . 1977, 42, 1821), and the coupling with arylboronic esters according to the method of Suzuki et al. (Chem. Letters 1989, 1405). Appropriate solvents for reactions of this type usually include tetrahydrofuran, diethyl ether, dimethylformamide, or dimethylsulfoxide. Typical temperatures range from ambient up to the boiling point of the solvent. Once coupled, the P group may be removed to afford compound (II). Conditions for the removal of the protecting groups are well known to those familiar to the art of organic synthesis; e.g. hydrogenation to remove benzyl or benzyloxycarbonyl, a fluoride source (such as tetrabutylammonium fluoride) to remove silylethoxymethyl, an acid source (such as trifluoroacetic acid) to remove tert-butoxycarbonyl or 4-methoxybenzyl, etc.

Compounds of formula (III) can be prepared according to the plan shown in Scheme 3. ##STR00012## A diamine compound of formula (V) (in this case, P is a group such as benzyl, which can be introduced already attached to the nitrogen atom; otherwise, P could represent H initially, and another protecting group being introduced in a later step) is used in a cyclocondensation reaction to make the imidazole ring. The conditions used will, of course, depend on the X group chosen, and may include the intermediacy of the compound (VI). A review of imidazole-forming reactions may be found in Comprehensive Heterocyclic Chemistry (Pergamon Press, 1984) vol. 5, pp. 457-498.

Preparation of compounds of formula (V) wherein both A and B are nitrogen atoms may proceed according to the route of Scheme 4. ##STR00013## A compound of formula (VII) may be available from commercial sources, particularly for K=chloride. Compounds bearing pseudohalide K groups may be available from the corresponding dihydroxy compounds by treatment with an appropriate activating reagent, such as an organosulfonic anhydride or sulfonyl chloride.

Compound (VII) may be converted to (V) by either (i) monoalkylation with a compound P--NH.sub.2, followed by reduction of the nitro group; (ii) reduction of the nitro group, to give an amine compound of formula (VIII), followed by monoalkylation with a compound P--NH.sub.2; or (iii) use of a source of ammonia (ammonia gas, ammonium hydroxide, etc.) in either route, followed by protection of the amine group with the group P. Pyrimidine chemistry of this type is well represented in the literature, and is reviewed in Comprehensive Heterocyclic Chemistry, vol. 6. Alkylation of chloropyrimidines with amine compounds can be accomplished under either acidic (e.g. HCl or acetic) or basic (trialkylamines, potassium tert-butoxide, etc.) conditions. Nitro groups in compounds of this type can be reduced to amino groups using one of any number of conditions, including catalytic hydrogenation, tin dichloride, sodium dithionite, zinc metal, iron powder, etc.

Preparation of compounds of formula (V) wherein either A or B represent nitrogen atoms is shown in Scheme 5. ##STR00014## An hydroxypyridone compound of formula (IX) can be nitrated to give compound (X), employing conditions such as concentrated or fuming nitric acid, optionally in the presence of concentrated sulfuric or acetic acid. The hydroxypyridone can be selectively monoactivated with a K group to give a compound of formula (XI); one method to do this involves treatment of the dicyclohexylamine salt of compound (X) with phosphorus oxychloride to give (XI) wherein K=Cl.

Alternatively, both the hydroxy and pyridone groups in compound (X) can be activated at the same time, using stronger conditions such as phosphorus oxychloride and heat, or excess toluenesulfonic anhydride, to give compound (XII). Compound (XI) may be converted to the protected amine compound (XIII) using the same general route discussed above for the pyrimidines. Selective monoalkylation using compound (XII) is also possible, but will probably give mixtures of regioisomeric products (XIV) and (XV). The nitro groups in these compounds can then be reduced as discussed above, to give compounds of formula (V), wherein either A or B is nitrogen.

An alternative approach to the method involving introduction of the R.sup.1 group at the final step is shown in Scheme 6. ##STR00015## This is particularly useful in the cases where R.sup.1 represents a group where alkylation of compound (II) is impractical (e.g. a very bulky R.sup.1 group), but can also be used in a general manner. Here, compounds of formula (XVI) or (XVII) (either amino- or nitro-pyridines or pyrimidines) are alkylated with an amine reagent R.sup.1--NH.sub.2, under either acidic or basic conditions as described above.

Nitro compound (XVIII) can be converted to amine compound (XIX) by nitro reduction reactions described earlier. Compound (XIX) can be cyclized to imidazole compound (XX). As above, this reaction will depend upon the choice of X group. For example, for X.dbd.CHR.sup.9, one can use an orthoester reagent such as R.sup.2CH(R.sup.9)C(OR).sub.3, with heating in neat solution or high-boiling solvents, and the optional presence of an acid catalyst (such as hydrochloric or sulfuric acid) (see Montgomery and Temple, J. Org. Chem . 1960, 25, 395). For X.dbd.NR.sup.10, the cyclization is performed using reagents such as an guanidine reagent of the structure R.sup.2R.sup.10N--C(.dbd.NH)NH.sub.2 or a urea-derived reagent of the structure R.sup.2R.sup.10N--C(.dbd.NH)D, where D represents a group like OCH.sub.3, SCH.sub.3 or SO.sub.2CH.sub.3. For X.dbd.O, the ring is formed using a reagent of the structure (R.sup.2O).sub.4C (with acetic acid catalysis), provided one has access to the reagent with the R.sup.2 group of choice (see Brown and Lynn, J. Chem. Soc. Perkin Trans. I 1974, 349). Alternatively, the diamine (XIX) is treated with phosgene, followed by O-alkylation to introduce the R.sup.2 group (such as a reagent like R.sup.2--I or R.sup.2--Br).

A similar route can be used for X.dbd.S, which would use thiophosgene or some similar reagent, followed by S-alkylation with the R.sup.2 group. The sulfur atom in this compound (and sulfide groups throughout the molecule in general) can be oxidized to either the sulfoxide or sulfone if desired by treatment with an appropriate oxidizing agent such as potassium permanganate, potassium peroxomonosulfate or m-chloroperbenzoic acid. Finally, compound (XX) can be used in an aryl coupling reaction as described above to replace the K group with the desired aryl group in compound (I).

Methods of synthesis of compounds R.sup.1--OH, R.sup.1--J and R.sup.1--NH.sub.2 are related, in that the alcohol can be used in the synthesis of the other two compounds, as is shown in Scheme 7. ##STR00016## For example, the hydroxy group may be converted to the following J groups, using the indicated reagents (this route is not limited to these J groups): methanesulfonate, using methanesulfonyl chloride or anhydride and an appropriate base; toluenesulfonate, using toluenesulfonyl chloride or anhydride and an appropriate base; iodide; using iodine/triphenylphosphine; bromide, using phosphorus tribromide or carbon tetrabromide/triphenylphosphine; or trifluoromethanesulfonate, using trifluoromethane-sulfonic anhydride and an appropriate base.

Both compounds R.sup.1--OH and R.sup.1--J are used in the methods portrayed in Scheme 1. Conversion of R.sup.1--J to R.sup.1--N.sub.3 requires the use of an azide source, such as sodium azide, and a solvent such as dimethylsulfoxide or dimethylformamide, or water and a phase-transfer catalyst (such as tetrabutylammonium hydrogen sulfate). Reduction of the azide compound R.sup.1--N.sub.3 to R.sup.1--NH.sub.2 may be accomplished using reagents such as sodium borohydride or triphenylphosphine, or hydrogen gas and a catalyst (such as palladium on carbon). The amine R.sup.1--NH.sub.2 may then be employed in the methods portrayed in Scheme 6.

In the cases where the compound R.sup.1--OH could be represented by a structure of formula (XXI) (Scheme 8), wherein R.sup.1a and R.sup.1b represents substructures which, taken together with the carbinol methine group, comprise the entire group R.sup.1, this compound may be prepared by addition to a carbonyl compound. ##STR00017## This route is particularly useful in the case where R.sup.1a or R.sup.1b represents a cycloalkyl group, such as cyclopropyl. An organometallic reagent (where M' represents a metallic group, such as Li, CuCN, CuI, MgCl, MgBr, MgI, ZnCl, CrCl, etc.) can be allowed to react with an aldehyde reagent to prepare the alcohol compound of formula (XXI).

Alternatively, a ketone of formula (XXII) may be treated with a reducing agent, such as sodium borohydride, lithium aluminum hydride, etc., which will also generate the alcohol of formula (XXI). Standard methods of ketone synthesis may be used where appropriate in the preparation of compounds for formula (XXII), which will be familiar to those skilled in the art of organic synthesis.

An homologous approach may also be employed in the synthesis of alcohols R.sup.1--OH, involving the ring-opening reaction of cyclic ether compounds with organometallic reagents (Scheme 9). ##STR00018## Here, an organometallic reagent R.sup.1a--M'' is used, where M'' represents metals such as Mg, Zn or Cu. Especially useful is the method described in Huynh, et al., Tetrahedron Letters 1979, (17), pp. 1503-1506, where organomagnesium reagents are allowed to react with cyclic ethers with catalysis provided by copper(I) iodide. Use of an epoxide compound of formula (XXIII) in this manner would result in synthesis of an alcohol compound of formula (XXIV), and use of an oxetane compound of formula (XXV) would generate an alcohol of formula (XXVI). Both compounds (XXIV) and (XXVI) are variants of R.sup.1--OH.

Synthesis of compound R.sup.1--NH.sub.2 with formula (XXVII) is portrayed in Scheme 10. ##STR00019## A simple reductive amination of ketone (XXII) will produce amine (XXVII). This reaction may be performed using anhydrous ammonia in the presence of hydrogen and a catalyst.

Alternatively, addition of an organometallic reagent to a nitrile compound gives an imine, which may be treated in situ with a reducing agent (such as sodium cyanoborohydride) to give the corresponding amine (XXVII). Finally, a compound of formula (XXVIII), wherein Q is an optionally-substituted oxygen atom (i.e. an oxime) or nitrogen atom (i.e. a hydrazone), may be allowed to react with an organometallic reagent R.sup.1b--M'''. Here, metallic groups M''' such as MgBr, CuCl or CeCl.sub.2 have been used in additions to oximes or hydrazones. The intermediate addition products of formula (XXIX) may be subjected to reductive cleavage (using conditions such as sodium/liquid ammonia or catalytic hydrogenation), which will afford amines (XXVII).

Amino acids, either naturally-occurring or synthetic, are potential sources of useful starting materials for the synthesis of the compounds of this invention. Scheme 11 shows some possible applications of this approach. ##STR00020## Protected amino acids of formula (XXXI) are prepared from the parent compounds of formula (XXX); useful protecting groups ("Prot") include tert-butoxycarbonyl, benzyloxycarbonyl and triphenylmethyl. Standard texts in peptide chemistry describe this protection. The carboxylic acid group may be reduced using reagents such as lithium borohydride, which gives alcohol (XXXII). The hydroxy group may be converted to a leaving group "J" as described before. The compound of formula (XXXIII) may be treated with appropriate reagents to produce a wide variety of functional groups included in the scope of this invention (compound (XXXIV)); displacement of J with cyanide (sodium cyanide in warm dimethylformamide may be used here) gives a nitrile, displacement of J with a mercaptan (in the presence of a base, such as potassium carbonate) gives a disulfide, displacement of J with a secondary amine gives a tertiary amine, etc.

Haloalkoxy-substituted aromatic groups (i.e., as ring D, either phenyl or pyridyl, having one or more haloalkoxy groups as substituents on the ring) may be introduced at several positions in the synthesis. For example, a reagent D--M (compound IV) may be prepared, wherein M is a metal suitable for cross-coupling with a heterocyclic compound (formula III, see above). In this case, the D group bears the haloalkoxy group, which is prepared according to methods discussed below. Alternatively, the complete molecule of Formula (I) with a phenolic OH substituent on the D group is treated with appropriate reagents to effect incorporation of the haloalkoxy functionality.

Phenolic groups are converted to haloalkoxy groups by haloalkyl alkylating reagents. For example, treatment of sodium phenolates (available from phenols upon treatment with basic reagents such as sodium hydride in appropriate solvents) with reagents such as 2,2,2-trifluoroethyl methanesulfonate (according to the method of F. Camps, J. Coll, A. Messeguer and M. A. Pericas, Synthesis 1980, p. 727) or 2,2,2-trifluoroethyl p-toluenesulfonate (according to the method of D. Preschler, T. Thiele and R. Ruhmann, J. Fluorine Chem. 1996, 79, p. 145-148) gives the corresponding aryl group substituted with a 2,2,2-trifluoroethoxy group. Many trifluoromethoxy-substituted aromatic reagents are available from commercial sources, which may be used to prepare compounds of the formula type IV by standard organic chemistry. Where the appropriate starting material is not available, phenolic OH groups are converted into trifluoromethoxy groups by treatment with reagents such as trifluoroacetic acid (according to Grinberg, et al., Izv. Akad. Nauk SSSR, Ser. Khim. 1997, p. 1505-1508) or carbon tetrachloride and antimony trifluoride with catalytic antimony pentachloride (according to Dow Chemical Co., U.S. Pat. No. 4,950,802).

Trifluoromethoxy aryl compounds are also made by conversion of a phenol to an intermediate group and subsequent fluorination to the desired product. Examples: are 1) the reaction of dithiocarbonates with 1,3-dibromo -5,5-dimethylpyrrolidine-2,4-dione/pyridinium fluoride (according to M. Kuroboshi, K. Suzuki and T. Hiyama, Tetrahedron Lett. 1992, 33, p. 4173-4176); 2) the reaction of aryl thiochloroformates with molybdenum hexafluoride (according to F. Mathey and J. Bensoam, Tetrahedron Lett.1973); and 3) the reaction of aryl fluoroformates with sulfur tetrafluoride/HF/sodium fluoride (according to W. A. Sheppard, J. Org. Chem. 1964, 29), all which afford trifluoromethoxy aryl compounds. Difluoromethoxy groups are prepared from phenols by treatment with chlorodifluoromethane in the presence of sodium hydroxide (according to S. V. Shelyazhenko, Y. A. Fialkov and L. M. Yagupol'skii, J. Org. Chem. (Russia) 1992, p. 1317-1323). Shelyazhenko et al. also teaches the chlorination of such difluoromethoxy aryl groups to give aryl chlorodifluoromethoxy compounds. Other haloalkoxy compounds may be prepared by Mitsunobu-type coupling of phenols with halo-substituted alcohols (employing reagents like diethyl azodicarboxylate and triphenylphosphine).

Also provided herein are compositions comprising the compounds of this invention, particularly pharmaceutical compositions comprising pharmaeutically acceptable carriers and therapeutically effective amounts of the compounds provided herein. "Pharmaceutically acceptable carriers" are media generally accepted in the art for the delivery of biologically active agents to mammals, e.g., humans. Such carriers are generally formulated according to a number of factors well within the purview of those of ordinary skill in the art to determine and account for. These include, without limitation: the type and nature of the active agent being formulated; the subject to which the agent-containing composition is to be administered; the intended route of administration of the composition; and, the therapeutic indication being targeted. Pharmaceutically acceptable carriers include both aqueous and non-aqueous liquid media, as well as a variety of solid and semi-solid dosage forms. Such carriers can include a number of different ingredients and additives in addition to the active agent, such additional ingredients being included in the formulation for a variety of reasons, e.g., stabilization of the active agent, well known to those of ordinary skill in the art. Descriptions of suitable pharmaceutically acceptable carriers, and factors involved in their selection, are found in a variety of readily available sources, e.g., Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., 1985, the contents of which are incorporated herein by reference.

"Therapeutically effective amounts" of biologically active agents are amounts effective to lessen, inhibit or prevent diseases and disorders in mammals, or the symptoms thereof. Such amounts include optimal and suboptimal doses, and can be determined in a variety of ways known to ordinarily skilled artisans, e.g., by administering various amounts of a particular agent to an animal afflicted with a particular condition and then determining the effect on the animal. Typically, therapeutically effective amounts of biologically active agents range from about 0.1 mg per kg of a mammal being treated to about 100 mg per kg, although amounts outside this range can also be therapeutically effective under a variety of conditions.

In particular, therapeutically effective amounts of the compounds of this invention are amounts effective to antagonize, or lower, levels of corticotropin releasing factor (CRF) in mammals, thereby alleviating in the mammals conditions characterized by abnormally high levels of CRF expression. In this regard, CRF is known to have a broad extrahyopthalamic distribution in the CNS, contributing therein to a wide spectrum of autonomic, behavioral and physiological effects (see, e.g., Vale et al., 1983; Koob, 1985; and, De Souza et al., 1985). For example, CRF concentrations are significantly increased in the cerebrospinal fluid of patients afflicted with affective disorder or major depression (see, e.g., Nemeroff et al., 1984; Banki et al., 1987; France et al., 1988; Arato et al., 1989), and thus, antagonism of CRF should ameliorate these conditions.

Moreover, excessive levels of CRF are known to produce anxiogenic effects in animal models (see, e.g., Britton et al., 1982; Berridge and Dunn, 1986 and 1987), and, CRF antagonists are known to produce anxiolytic effects; accordingly, therapeutically effective amounts of compounds provided herein are, for example, determined by assessing the anxiolytic effects of varying amounts of the compounds in such animal models. Furthermore, clinical data provides evidence that CRF has a role in psychiatric disorders and neurological diseases including depression, anxiety-related disorders and feeding disorders; a role for CRF has also been postulated in the etiology and pathophysiology of Alzheimer's disease, Parkinson's disease, Huntington's disease, progressive supranuclear palsy and amyotrophic lateral sclerosis as they relate to the dysfunction of CRF neurons in the central nervous system (see, e.g., E. B. De Souza, 1988).

Neurochemical, endocrine and receptor binding studies have all demonstrated interactions between CRF and benzodiazepine anxiolytics, providing further evidence for the involvement of CRF in these disorders. Chlordiazepoxide attenuates the "anxiogenic" effects of CRF in both the conflict test [K. T. Britton et al., Psychopharmacology 86:170 (1985); K. T. Britton et al., Psychopharmacology 94:306 (1988)] and in the acoustic startle test [N. R. Swerdlow et al., Psychopharmacology 88:147 (1986)] in rats. The benzodiazepine receptor antagonist (Ro15-1788), which was without behavioral activity alone in the operant conflict test, reversed the effects of CRF in a dose-dependent manner while the benzodiazepine inverse agonist (FG7142) enhanced the actions of CRF [K. T. Britton et al., Psychopharmacology 94:306 (1988)].

The contents of the above-cited disclosures are incorporated herein by reference.

Accordingly, antagonism of CRF by compounds of this invention is an effective means of treating conditions such as affective disorder, depression and anxiety. Additional treatable conditions include, without limitation: headache, irritable bowel syndrome, post-traumatic stress disorder, supranuclear palsy, immune suppression, Alzheimer's disease, Huntington's disease, Parkinson's disease, progressive supranuclear palsy, amyotrophic lateral sclerosis, gastrointestinal diseases, anorexia nervosa or other feeding disorder, drug addiction, drug or alcohol withdrawal symptoms, inflammatory diseases, cardiovascular or heart-related diseases, fertility problems, human immunodeficiency virus infections, hemorrhagic stress, obesity, infertility, head and spinal cord traumas, epilepsy, stroke, ulcers, amyotrophic lateral sclerosis and hypoglycemia. Therefore, this invention further provides a method of treating such conditions, said method comprising administering to mammals afflicted with the conditions a dose of a pharmaceutical composition provided herein.

However, those of ordinary skill in the art will readily understand that these examples are not intended to be limiting, and are merely illustrative of the invention as defined in the claims which follow thereafter.
