Description: SUBSTITUTED AZEPINO[4,5b]INDOLINE DERIVATIVES Cross Reference To Related Applications This application claims priority from United States Provisional Application Number 60/234,376, filed 20 September 2000; United States Provisional Application Number 60/266,047, filed 1 February 2001; and United States Provisional Application Number 60/301,964, filed 29 June 2001. BACKGROUND OF THE INVENTION Field of the Invention The present invention generally relates to a series of compounds, to pharmaceutical compositions containing the compounds, and to use of the compounds and compositions as therapeutic agents. More specifically, compounds of the present invention are octahydroazepinoindole compounds. These compounds are serotonin receptor (5-HT) ligands and are useful for treating diseases, disorders, and conditions wherein modulation of the activity of serotonin receptors (5-HT) is desired (e.g. anxiety, depression or obesity). Brief Description of Related Technology Serotonin has been implicated in a number of diseases, disorders, and conditions that originate in the central nervous system, including diseases, disorders, and conditions related to, for example, sleeping, eating, perceiving pain, controlling body temperature, controlling blood pressure, depression, anxiety, and schizophrenia. Serotonin also plays an important role in peripheral systems, such as the gastrointestinal system, where it has been found to mediate a variety of contractile, secretory, and electrophysiologic effects. Because of the broad distribution of serotonin within the body, a heightened interest exists for drugs that affect serotonergic systems. In particular, agonists, partial agonists, and antagonists of serotonergic systems are of interest for the treatment of a wide range of disorders, including anxiety, depression, hypertension, migraine, obesity, compulsive disorders, schizophrenia, autism, neurodegenerative disorders (e.g., Alzheimer's disease, Parkinsonism, and Huntington's chorea), and chemotherapy-induced vomiting. The major classes of serotonin receptors (5-HT 1- ) contain fourteen to eighteen separate receptors that have been formally classified. See Glennon, et al., Neuroscience and Behavioral Reviews, 1990, 14, 35; and D. Hoyer, et al. Pharmacol. Rev. 1994, 46, 157-203. For example, the 5-HT 2 family of receptors contains 5-HT A , 5- HT B , and 5-HT 2 c subtypes, which have been grouped together on the basis of primary structure, secondary messenger system, and operational profile. All three 5-HT 2 subtypes are G-protein coupled, activate phospholipase C as a principal transduction mechanism, and contain a seven-transmembrane domain structure. There are distinct differences in the distribution of the three 5-HT 2 subtypes in a mammal. The 5-HT 2B and 5-HT A receptors are widely distributed in the peripheral nervous system, while the 5-HT 2 c receptor has been found only in the central nervous system, being highly expressed in many regions of the human brain. See G. Baxter, et al. Trends in Pharmacol. Sci. 1995, 16, 105-110. Subtype 5-HT A has been associated with effects including vasoconstriction, platelet aggregation, and bronchoconstriction, while subtype 5- HT c has been associated with diseases that include depression, anxiety, obsessive compulsive disorder, panic disorders, phobias, psychiatric syndromes, and obesity. Very little is known about the pharmocologic role of the 5-HT B receptor. See F. Jenck, et al., Exp. Opin. Invest. Drugs, 1998, 7, 1587-1599; M. Bos, et al., J. Med. Chem., 1997, 40, 2762-2769; J.R.

The mesylate (45) is treated with a suitable azide such as sodium azide in DMF, to yield an azide (48). This azide is reduced by catalytic hydrogenolysis (e.g., H 2 , 10% Pd/C, ethyl acetate, ethanol) to yield an amine (49). The amine (49) is treated with a suitable acid solution, such as TFA in CH 2 C1 2 , and the resulting crude diamine can be treated with a suitable acid solution, such as HCl in ethyl' ether, to yield the dihydrochloride salt of (50). Intermediate compounds of Formula (IV) (wherein R 3 = (CH 2 ) n NHCONHAr) can be prepared by the reaction scheme depicted in Figure 18. The amine (49) is treated with aryl isocyanate in CH 2 C1 2 to yield urea (51). The urea (51) is treated with a suitable acid solution, such as TFA in CH 2 C1 2 , and the resulting crude amine ccan be treated with a suitable acid solution, such as HCl in ethyl ether, to yield hydrochloride salt of (52). Intermediate compounds of Formula (IV) (wherein R 3 = (CH 2 ) n NHCOAr) can be prepared by the reaction scheme depicted in Figure 19. The amine (49) is treated with a suitable aroyl chloride, in the presence of a suitable basic solution, such as diisopropylethylamine in CH 2 C1 2 , to yield an amide (53). The amide (53) is treated with a suitable acid solution, such as TFA in CH 2 C1 2 , and the resulting crude amine may be treated with a suitable acid solution, such as HCl in ethyl ether, to yield hydrochloride salt of (54). Intermediate compounds of Formula (IV) (wherein R 3 = (CH 2 ) n NHSO 2 Ar) can be prepared by the reaction scheme depicted in Figure 20. The amine (49) is treated with a suitable arylsulfonyl chloride, in the presence of a suitable basic solution, such as diisopropylethylamine in CH 2 C1 2 , to yield sulfonamide (55). The sulfonamide (55) is treated with a suitable acid solution, such as TFA in CH 2 C1 2 , and the resulting crude amine may be treated with a suitable acid solution, such as HCl in ethyl ether, to yield hydrochloride salt of (56). Intermediate compounds of Formula (IV) (wherein R 2 = 5,5-di- Me) can be prepared by the reaction scheme depicted in Figure 21. The phthalimido-protected tryptamine (57) is reverse prenylated, using the procedures described by Depew et al. (J. Am. Chem. Soc. 1996, 77S, 12463) and Schkeryantz et al (J. Am. Chem. Soc. 1999, 727, 11964), to provide (58). Standard deprotection of (58) (e.g., NH 2 NH 2 , EtOH) provides (59). The amine group of (59) is re-protected (e.g., CbzCl) to provide (60). Oxidation of the vinyl group of (60) (e.g., OsO 4 , NMO) provides diol (61), that is oxidatively cleaved (e.g., NaIO 4 ) to aldehyde (62). Mild catalytic hydrogenation of (62) accomplishes Cbz deprotection, that is followed by in situ intramolecular cyclization to the imine and imine reduction, to provide an amine (63), which may be formulated as the hydrochloride salt. Intermediate compounds of Formula (IV) can be prepared by the reaction scheme depicted in Figure 22. Acylation of 4-chloroindole (64) (oxalyl chloride, followed by an EtOH quench) provides an ethyl 4-chloroindole glyoxalate (65), which is reduced (e.g., LiAlH 4 ) to the 4-chloroindole-3-ethanol (66). Substitution of the alcohol (66) is achieved using a suitable azide, such as Zn(N 3 ) 2 , under Mitsunobu reaction conditions to provide (67). Malonate addition to (67) is accomplished as described by Kuehne J. Org. Chem., 63, 9427 (1998), to provide a malonyl enolate (68). Alkylation of the malonyl enolate (68) with a suitable alkylating agent such as NaOMe and Mel, provides (69). The azide group of (69) is reduced (sequential addition of PMe 3 and H 2 O) to provide an aminoester (70). The aminoester (70) undergoes intramolecular cyclization, providing lactam (71) upon reflux as a solution in MeOH. Racemate (71) is separated into the enantiomers (72) and (73) by chiral support chromatography. The assignment of the absolute configurations to (72) and (73) is made by x-ray crystallographic analysis. The lactam group of each enantiomer is separately reduced (BH 3 ) to provide amines (74) (from reduction of (72)) and (75) (from reduction of (73)), which may be formulated as the fumarate salts. Intermediate compounds of Formula (IV) (wherein R 4 = 7-F) can be prepared by the reaction scheme depicted in Figure 23. Beginning with 6- fluoroindole (76), the preparation of intermediates (77), (78), (79), and (80) follows the methods described respectively for (65), (66), (67), and (68) (Figure 22). The azido group of (80) is reduced by catalytic hydrogenation, and the resulting aminoester is subjected (without isolation) to thermal cyclization to provide (81). Reduction (e.g., BH 3 ) of the lactam of (81) provides an amine (82), which may be formulated as the fumarate salt. Intermediate compounds of Formula (IV) (R 4 = 7-F) can be prepared by the reaction scheme depicted in Figure 24. According to the reaction sequence of Figure 23, alkylation of the malonyl enolate of (80), as described previously for the preparation of (69), provides (83). Racemate (83) is separated into the enantiomers (84) and (85) by chiral support chromatography. The assignment of the absolute configurations to (84) and (85) is made by correlation of their CD spectra to those of (72) and (73). The lactam group of each enantiomer is separately reduced with a suitable reducing agent such as BH 3 , to provide amines (86) (from reduction of (84)) and (87) (from reduction of (85)), which may be formulated as the fumarate salts. As shown in Figure 25, compounds of Formula (IV) may also be prepared starting with the corresponding nitrobenzenes (96), benzoic acids (97) or anilines (98), many of which are commercially available or known in the scientific literature, or can be prepared by general procedures known to those skilled in the art (for examples, see Larock, R.C., Comprehensive Organic Transformations, 2 nd edition, 1999, Wiley- VCH Publishers, New York). For example, reduction of the nitro group using a variety of conditions or reagents such as SnCl 2 in acid, LAH, sodium borohydride, hydrazine, or hydrogen in the presence of appropriate catalysts such as palladium, platinum, nickel, etc (see Hudlicky, M. "Reductions in Organic Chemistiy", 1984, Ellis Horwood, Ltd., Chichester, UK) gives the corresponding anilines (98). Alternatively, benzoic acids (97) can be converted to the corresponding anilines (98) via reactions known to those in the art, such as the Curtius reaction, (for examples, see Larock, R.C., Comprehensive Organic Transformations, 2" edition, 1999, Wiley- VCH Publishers, New York, 868-869). Conversion of these anilines to the corresponding phenylhydrazines (99) can be accomplished through the well- known nitrosation reduction sequence (e.g., treatment of (98) with NaNO 2 under acidic conditions, such as HOAc, followed by reduction of the resulting N- nitrosoamine with agents such as lithium aluminum hydride or zinc and an organic acid such as acetic or trifluoracetic acid). Reaction of (99) with ketones, such as l-benzoylazepan-4-one, under Fisher-indole cyclization conditions as described, for example, in "Indoles, Best Synthetic Methods" (Academic Press, 1999, San Diego, CA) produces azepinoindoles (100). These compounds can be treated as described above to give azepinoindoles (88) and (89). Intermediate (7, 8, 9, or 10-) aminoazepinoindoles (Formula (IV) wherein R 4 = ΝR a R b ), can be prepared by the reactions depicted in Figure 26. As shown in Figure 26, a (7, 8, 9, or 10-) bromoazepinoindole (116) is coupled with an amine via palladium catalysis (for example, see Buchwald et al, J. Org. Chem. 2000, 65, 1158-1174). When R 3 = H, the final product (119) can then be generated by deprotection of compound (117) using the methods found in Green, T.W.; Wuts, P.G.M. Protective Groups in Organic Synthesis, 3 rd edition, 1999, John Wiley & Sons, Inc., New York. Alternatively, an R group can be installed using the methods described above to give compound (118), which is then deprotected. Compounds of Formula (I) can be prepared by the reaction scheme depicted in Figure 27. Azepinoindoles (88) are known in the literature for R 3 = H (See J. Med. Chem., 1968, 77, 101-106) or can be prepared as described herein. When R 1 is benzoyl, amines (89) can be obtained from basic hydrolysis (e.g., potassium hydroxide in ethylene glycol). Alternatively, when R is Boc, amines (89) can be obtained under acidic conditions such as TFA in CH 2 C1 2 . Reduction of (89) under conditions such as sodium cyanoborohydride (or sodium triacetoxyborohydride) in acidic solvents such as trifluoroacetic acid gives α ' s-azepinoindolines (90). Separation of c/s-enantiomers (91) and (92) is carried out through resolution techniques know in the art, such as chromatographic resolution using a chiral stationary phase (normal or reverse phase) or using a traditional fractional crystallization of diastereomeric salts derived using readily-available chiral acids such as (d)- or (l)-tartaric acid or their derivatives (see for example Kinbara, et al, J. Chem. Soc, Perkin Trans., 2, 1996, 2615 and Tomori, et al Bull. Chem. Soc. Jpn., 1996, 3581). Reduction of (89) under conditions such as treatment with borane-tetrahydrofuran complex followed by water and triflμoroacetic acid (see for example Tetrahedron Letters, 1982, 23, 1983-1984) gives trαrcs-azepinoindolines (90). Resolution of trans- enantiomers (93) and (94) is carried out as described above for the cw-isomers. Compounds of Formula (I) also can be prepared by the reaction scheme depicted in Figure 28. Reduction of the azepinoindoles (88) with suitable reducing agents, such as sodium cyanoborohydride in TFA/MeOH, yields a separable mixture of cis- and trαns-azepinoindolines (95). When R 1 is benzoyl, deprotected azepinoindolines (90) can be obtained from basic hydrolysis (e.g., potassium hydroxide in ethylene glycol). Alternatively, when R 1 is Boc, deprotected azepinoindolines (90) can be obtained under acidic conditions such as TFA in CH 2 C1 2 . If desired, resolution of (90) or (95) may be carried out as described above. Figure 29 shows yet another method for obtaining compounds of Formula (I). Bromoazepinoindoles (101) are competent partners for transition metal catalyzed coupling reactions with aryl boronic acids to give azepinoindoles (102) (for examples of the Suzuki reaction; see Miyaura, N., et al, Chem. Rev., 1995, 2457 and referenced therein). Typically, the Suzuki reaction is carried out using a palladium catalyst (such as Pd(PPh 3 ) 4 , Pd(PPh 3 ) 2 Cl 2 , Pd(OAc) 2 , Pd 2 (dba) 3 , etc), a suitable ligand (such as PPh 3 , Pt-Bu 3 , Pcy 3 , etc), a base (such as Na 2 CO 3 , Cs 2 CO 3 , amines, etc) in a solvent such as DMF, toluene, dioxane, or the like. Removal of the R 1 protecting group by the methods described above gives amines (103). Reduction of (103) with suitable reducing agents, such as sodium cyanoborohydride in TFA/MeOH, yields azepinoindolines (104). Further elaboration of (104), such as chloronation using NCS (for examples, see Larock, R.C., Comprehensive Organic Transformations, 2 nd edition, 1999, Wiley- VCH Publishers, New York), can be done to give more highly substituted azepinoindolines (105). Compounds of Formula (I) can also be prepared as shown in Figure 30. Bromoazepinoindolines (106) where R 1 is benzoyl are deprotected via basic hydrolysis (e.g., potassium hydroxide in ethylene glycol) to give amines (107). The reduction of (107) is accomplished with suitable reducing agents as described above to give azepinoindolines (108) which can then be protected to give (109) using, for example, excess di-tert-butyl dicarboxylate in THF/aqueous base (such as sodium hydroxide or potassium carbonate). Subjection of (109) to Suzuki reaction conditions as described above leads to azepinoindolines (110), which are deprotected to give amines (111). When R 1 is Boc, the deprotection can be accomplished via acidic conditions such as TFA/CH 2 C1 2 or treatment with acidic resin (for example, Dowex ® 50WX2-400 ion-exchange resin). Compounds of Formula (I) can also be prepared following the sequence in Figure 31. Azepinoindoles (112) are alkylated (for example, NaH and β-bromophenetole in DMF) to give 6-substituted azepinoindoles (113). These compounds are deprotected using the methods described above to give amines (114). Reduction of (114) with suitable reducing agents as described above leads to azepinoindolines (115). Compounds of Formula (I) can also be prepared as shown in Figure 32. Ester-containing azepinoindole (39) is reduced to azepinoindoline (120) using suitable agents, such as sodium cyanoborohydride in TFA/MeOH. The protecting group R 1 is introduced to give compound (121) using standard conditions (such as those described in Green, T.W.; Wuts, P.G.M. Protective Groups in Organic Synthesis, 3 rd edition, 1999, John Wiley & Sons, Inc., New York). The ester is hydrolyzed to the acid (122) using basic conditions such as KOH in THF/H 2 O. Amide (123) is prepared from acid (122) and an amine under coupling conditions such as EEDQ in THF or a carbodiimide with base in THF. Finally, removal of R 1 (using the methods such as those found in Green, T.W.; Wuts, P.G.M. Protective Groups in Organic Synthesis, 3 rd edition, 1999, John Wiley & Sons, Inc., New York) gives amide-containing azepinoindoline (124). The phrases "pharmaceutically acceptable salts" or "a pharmaceutically acceptable salt thereof refer to salts prepared from pharmaceutically acceptable acids or bases, including organic and inorganic acids and bases. Salts can be prepared from pharmaceutically acceptable acids. Pharmaceutically acceptable salts can be obtained using standard procedures known by those skilled in the art, for example by reacting a sufficiently basic compound, such as an amine, with a suitable acid affording a physiologically acceptable anion. Suitable pharmaceutically acceptable acids include acetic, benzenesulfonic (besylate), benzoic, /?-bromophenylsulfonic, camphorsulfonic, carbonic, citric, ethanesulfonic, fumaric, gluconic, glutamic, hydrobromic, hydrochloric, hydroiodic, isethionic, lactic, maleic, malic, mandelic, methanesulfonic (mesylate), mucic, nitric, oxalic, pamoic, pantothenic, phosphoric, succinic, sulfuric, tartaric, p-toluenesulfonic, and the like. Examples of such pharmaceutically acceptable salts, thus, include, but are not limited to, acetate, benzoate, β-hydroxybutyrate, bisulfate, bisulfite, bromide, butyne-1,4- dioate, carpoate, chloride, chlorobenzoate, citrate, dihydrogenphosphate, dinitrobenzoate, fumarate, glycollate, heptanoate, hexyne-l,6-dioate, hydroxybenzoate, iodide, lactate, maleate, malonate, mandelate, metaphosphate, methanesulfonate, methoxybenzoate, methylbenzoate, monohydrogenphosphate, naphthalene- 1-sulfonate, naphthalene-2-sulfonate, oxalate, phenylbutyrate, phenylproionate, phosphate, phthalate, phylacetate, propanesulfonate, propiolate, propionate, pyrophosphate, pyrosulfate, sebacate, suberate, succinate, sulfate, sulfite, sulfonate, tartrate, xylene sulfonate, and the like. The compounds of the Formula (I) also can provide pharmaceutically acceptable metal salts, in particular alkali metal (e.g., sodium, potassium, magnesium, or lithium) salts and alkaline earth metal (e.g., calcium) salts, with bases. Compounds of Formula (I) are useful in treating diseases, disorders, and conditions of the central nervous system occurring in mammals. Typically, the mammal is a human being, but the compounds can be used to treat other animals such as livestock, pets, or other animals. It is to be understood that "a compound of Formula (I)," or a pharmaceutically acceptable (acidic or basic) salt or solvate (i.e., hydrate) thereof, can be administered as the neat compound, or as a pharmaceutical composition containing the compound in combination with a suitable excipient. Such pharmaceutical compositions can be prepared by methods and contain excipients which are known by those skilled in the art. A generally recognized compendium of such methods and ingredients is Remington 's Pharmaceutical Sciences by E.W. Martin (Mark Publ. Co., 15th Ed., 1975), the disclosure of which is incorporated herein by reference. In cases where a compound is sufficiently basic or acidic to form a stable pharmaceutically acceptable salt, administration of the compounds as a salt may be preferred. The compounds of this invention can be administered in oral unit dosage forms, such as aerosol sprays, buccal tablets, capsules, elixirs, pills, sachets, suspensions, syrups, tablets, troches, wafers, and the like. The compounds also can be administered parenterally, (e.g., subcutaneously, intravenously, intramuscularly, or by intraperitoneal injection), using forms known in the pharmaceutical art. The compounds further can be administered rectally or vaginally, in such forms as suppositories or bougies, transdermally, such as with a "patch" containing active ingredient, or nasally (i.e., by inhalation). In general, the preferred route of administration of a present compound is oral. For oral administration, the active compound can be combined with one or more excipients and used in the form of ingestible aerosol sprays, buccal tablets, capsules, elixirs, pills, sachets, suspensions, syrups, tablets, troches, wafers, and the like. Such compositions and preparations typically contain at least 0.1% of active compound. The percentage of the compounds in these preparations can be varied, e.g., about 0.01 to about 60% of the weight of a given unit dosage form. The amount of active compound in such orally administered compositions is sufficient to provide an effective dosage level. The aerosol sprays, buccal tablets, capsules, elixirs, pills, sachets, suspensions, syrups, tablets, troches, wafers, and the like also can contain one or more binders, diluents disintegrating agents, excipients, lubricants, sweetening agents, or flavoring agents. Suitable binders include, for example, gum arabic, tragacanth, acacia, polyvinylpyrrolidone, corn starch, methylcellulose, or gelatin. Suitable diluents include, for example, lactose, dextrose, sucrose, mannitol, sorbitol, and cellulose. Suitable disintegrating agents include, for example, starches, alginic acid, and alginates. Suitable excipients include dicalcium phosphate. Suitable lubricants include, for example, silica, talc, stearic acid, magnesium or calcium stearate, and/or polyethylene glycols. Suitable wetting agents include, for example, lecithin, polysorbates, and laurylsulfates. Generally, any effervescing agents, dyestuffs, and/or sweeteners known by those of ordinary skill in the art can be used in the preparation of a pharmaceutical composition. For example, suitable sweetening agents include sucrose, fructose, lactose or aspartame, and suitable flavoring agents include peppermint, oil of wintergreen, or cherry flavoring. The aforementioned ingredients are merely representative and one skilled in the art can envision other binders, excipients, sweetening agents, and the like. When the unit dosage form is a capsule, it can contain, in addition to ingredients of the above type, a liquid carrier (e.g., vegetable oil or a polyethylene glycol). Various other ingredients can be present as coatings or to otherwise modify the physical form of the solid unit dosage foπn. For instance, tablets, pills, or capsules may be coated with gelatin, wax, shellac, or sugar, and the like. A syrup or elixir can contain the active compound, sucrose or fructose as a sweetening agent, methyl and propyl parabens as preservatives, a dye and flavoring, such as cherry or orange flavor. Any material used in preparing any unit dosage form should be pharmaceutically acceptable and substantially non- toxic in the amounts employed. In addition, the active compound can be incorporated into sustained-release preparations and devices including, but not limited to, those relying on osmotic pressures to obtain a desired release profile (e.g., the OROS drug delivery devices as designed and developed by Alza Corporation, Mountain View, California). Orally administered compositions can be prepared by any method that includes the step of bringing the active compound into intimate association with a carrier, which constitutes one or more necessary or desirable ingredients. Generally, the compositions are prepared by uniformly and intimately admixing the active ingredient with liquid carriers, finely divided solid carriers, or both, and then, if necessary, shaping the product into a desired form. For example, a tablet can be prepared by compression or molding techniques, optionally, using one or more accessory ingredients. Compressed tablets can be prepared by compressing the active ingredient in a suitable machine into a free-flowing form, such as a powder or granules. Thereafter, the compressed, free-flowing form optionally can be mixed with binders, diluents, lubricants, disintegrating agents, effervescing agents, dyestuffs, sweeteners, wetting agents, and non-toxic and pharmacologically inactive substances typically present in pharmaceutical compositions. The pharmaceutical composition can contain about 5 to about 95%, and preferably about 25 to about 90%, of a compound of the present invention. Molded tablets can be made b molding a mixture of the powdered compound moistened with an inert liquid diluent in a suitable machine. Oral administration is the most convenient route of administration and avoids the disadvantages associated with other routes of administration. For patients suffering from a swallowing disorder or from impairment of drug absorption after oral administration, the drug can be administered by other methods, such as parenterally, rectally or vaginally, transdermally, and nasally. Parenteral administration is performed by preparing the composition containing the active compound. Solutions of the active compound or its salts can be prepared in water, optionally mixed with a nontoxic surfactant. Dispersions can also be prepared in glycerol, liquid polyethylene glycols, triacetin, and mixtures thereof and in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms. Pharmaceutical dosage forms suitable for parenteral administration (e.g., subcutaneously, intravenously, intramuscularly, or by intraperitoneal injection or infusion) can include sterile aqueous solutions or dispersions or sterile powders comprising the active ingredient which are adapted for the extemporaneous preparation of sterile injectable or infusible solutions or dispersions, optionally encapsulated in liposomes. In all cases, the ultimate dosage form should be sterile, fluid, and stable under the conditions of manufacture and storage. The liquid carrier or vehicle can be a solvent or liquid dispersion medium comprising, for example, water, ethanol, a polyol (e.g., glycerol, propylene glycol, liquid polyethylene glycols, and the like), vegetable oils, nontoxic glyceryl esters, and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the formation of liposomes, by the maintenance of the required particle size in the case of dispersions, or by the use of surfactants. The prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like. In many cases, it is preferable to include isotonic agents, for example, sugars, buffers, or sodium chloride. Prolonged absorption of the injectable compositions can be achieved by use of agents that delay absorption, for example, aluminum monostearate and gelatin. Sterile injectable solutions can be prepared by incorporating the active compound in the required amount in the appropriate solvent with various of the other ingredients enumerated above, as required, followed by filter sterilization. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum drying and the freeze drying techniques, which yield a powder of the active ingredient plus any additional desired ingredient present in the previously sterile-filtered solutions. Sterilization of the powders also can be accomplished through irradiation and aseptic crystallization methods known to persons skilled in the art. For parenteral administration, the active compounds are presented in aqueous solution in a concentration of about 0.1 to about 10%, more preferably about 0.1 to about 7%, by weight. The solution can contain other ingredients, such as emulsifiers-, antioxidants, or buffers. For topical administration, the present compounds can be applied in neat form, e.g., when the compound is a liquid. However, it is desirable to administer the compounds to the skin as compositions in combination with a dermatologically acceptable carrier, which can be a solid, semi-solid, or a liquid. Useful solid carriers include, but are not limited to, finely divided solids such as talc, clay, microcrystalline cellulose, silica, alumina, and the like. Useful liquid carriers include, but are not limited to, water, alcohols, glycols, and water- alcohol/glycol blends, in which the present compounds can be dissolved or dispersed at effective levels, optionally with the aid of a surfactant. Adjuvants, such as fragrances and additional antimicrobial agents, can be added to optimize the properties for a given use. The resultant liquid compositions can be applied topically by absorbent pads, used to impregnate bandages and other dressings, or sprayed onto the affected area using pump-type or aerosol sprayers. For administration by inhalation, compounds of the present invention can be delivered in the form of an aerosol spray presentation from pressurized packs or a nebulizer, with the use of a suitable propellant. In the case of a pressurized aerosol, the dosage unit can be determined by providing a valve to deliver a metered amount. Capsules and cartridges for use in an inhaler or insufflator can be formulated containing a powder mix of the compound and a suitable powder base, such as lactose or starch. Compounds of the present invention also can be formulated in rectal compositions, such as suppositories or retention enemas, e.g., containing conventional suppository bases. In addition to the formulations described previously, the compounds also can be formulated as a depot preparation. Such long-acting formulations can be administered by implantation (for example, subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, the compounds can be formulated with suitable polymeric or hydrophobic materials (for example, as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt. Generally, compounds of the invention are serotonin receptor (5- HT) ligands. The ability of a compound of the invention to act as a 5-HT receptor agonist, partial agonist, or antagonist can be determined using in vitro and in vivo assays that are known in the art. The invention provides compounds of Formula (I) that act as either agonists, partial agonists, or as antagonists of one or more 5-HT receptor subtypes. As used herein, the terms "treat," "treatment," and "treating," extend to prophylaxis, in other words "prevent," "prevention," and "preventing," lowering, stopping, or reversing the progression or severity of the condition or symptoms being treated. As such, the term "treatment" includes both medical therapeutic and/or prophylactic administration, as appropriate. The terms "prevent," "prevention," and "preventing" refer to an administration of the pharmaceutical composition to a person who has in the past suffered from the aforementioned diseases, disorders, or conditions, such as migraine headaches, but is not suffering from the diseases, disorders, or conditions at the time of the composition's administration. Compounds and pharmaceutical compositions suitable for use in the present invention include those wherein the active ingredient is administered in an effective amount to achieve its intended purpose. More specifically, a "therapeutically effective amount" means an amount effective to treat the disease, disorder, and/or condition. Determination of a therapeutically effective amount is well within the capability of persons skilled in the art, especially in light of the detailed disclosure provided herein. A "therapeutically effective dose" refers to that amount of the compound that results in achieving the desired treatment (or effect). Therapeutic efficacy of such compounds can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., for determining the LD 50 (the dose lethal to 50% of the population) and the ED 50 (the dose therapeutically effective in 50% of the population). The dosage can vary within this range depending upon the dosage form employed, and the route of administration utilized. The dosage regimen and amount for treating patients with the compounds of this invention is selected in accordance with a variety of factors including, for example, the type, age, weight, sex, and medical condition of the patient, the severity of the condition, and the route of administration. An ordinarily skilled physician or psychiatrist can readily determine and prescribe an effective amount of the compound to prevent or arrest the progress of the condition. In so proceeding, the physician or psychiatrist can employ relatively low initial dosages and subsequently increasing the dose until a maximum response is obtained. The compound is administered in unit dosage form, for example, containing about 0.05 to about 500 mg, preferably about 0.1 to about 250 mg, and more preferably about 1 to about 150 mg, of active ingredient per unit dosage form. The desired dose can be presented in a single dose, or as divided doses administered at appropriate intervals, for example, as two, three, four or more sub-doses per day. The sub-dose itself can be further divided, e.g., into a number of discrete loosely spaced administrations. The compositions can be administered orally, sublingually, transdermally, or parenterally at dose levels of about 0.01 to about 150 mg/kg, preferably about 0.1 to about 50 mg/kg, and more preferably about 0.1 to about 10 mg/kg of mammal body weight. The exact regimen for administration of the compounds and compositions disclosed herein necessarily depends upon the needs of the individual subject being treated, the patient type (i.e., human or animal), the type of treatment and, of course, the judgment of the attending practitioner or physician. In practice, the physician determines the actual dosing regimen which is most suitable for an individual patient, and the dosage varies with the age, weight, and response of the particular patient. The above dosages are exemplary of the average case, but there can be individual instances in which higher or lower dosages are merited, and such are within the scope of this invention. Specifically, for administration to a human in the curative or prophylactic treatment of the diseases, disorders, and conditions identified above, oral dosages of a compound of Formula (I) generally are about 0.5 to about 1000 mg daily for an average adult patient (70 kg). Thus, for a typical adult patient, individual tablets or capsules contain 0.2 to 500 mg of active, compound, in a suitable pharmaceutically acceptable vehicle or carrier, for administration in single or multiple doses, once or several times per day. Dosages for intravenous, buccal, or sublingual administration typically are 0.1 to 500 mg per single dose as required. For veterinary use, a compound of Formula (I), or a nontoxic salt thereof, is administered as a suitably acceptable formulation in accordance with normal veterinary practice.

Compounds identified in Examples 15-46 were prepared according to the following protocol (See Fig. 2): 1. Pinacol boronate (5.10 g, 12.4 mmol)) and 1,1' -bisdiphenylphosphine ferrocene (DPPF, 0.05 eq, 0.35 g, 0.62 mmol) were dissolved in 10% methanol in dioxane (degassed with argon) to a 100 mL volume. 2. Similarly, tris(dibenzylideneacetone)dipalladium (Pd 2 dba 3 , 0.03 eq, 0.34 g, 0.37 mmol) was dissolved in 10% methanol in dioxane (degassed with argon) to a 50 mL volume. 3. Cesium carbonate (1.5 eq, 0.12 g, 0.34 mmol) was weighed into labeled, 20 mL vials, and stored at room temperature overnight. A 4 mm glass bead and the appropriate aryl bromides (~3 eq) were added to the vials. 4. The pinacol boronate/DPPF solution above was added (1.8 mL to each vial) and the vials were purged with nitrogen and fitted with a Teflon- lined cap. 5. In an argon-filled glove-box, the palladium solution was added (0.9 mL to each vial). The tightly-capped vials were then placed in a heater block (90 °C) and shaken at 250 RPM overnight. After cooling to ambient temperature, sulfonic acid resin (BioRad Ag ® 50W-X2, washed and dried, 5.2 meq/g dry weight) was added, 18 eq to each vial (0.85 g) and also 1.8 mL of methanol. The vials then, were capped and agitated at 250 RPM with heating at 60 °C for 2 hours. The vials then were cooled to ambient temperature and emptied into 25 mL fritted plastic syringe barrels affixed to a wash receiver tank. The resin was washed into the syringe barrels with water and methanol as required to have all the reagents in solution. A battery of washings then was used to ensure that all excess reagent was removed from the resin: 2 x 3 mL each of water, methanol, tetrahydrofuran, and methylene chloride. The methanol and tetrahydrofuran washes can be alternated to swell and then shrink the resin to help expel reagents from inside the resin. The vials that contained basic reagents (e.g., pyridines) were also washed with 2M pyridine in methanol after the methanol washes. 8. The syringe barrels then were racked above tared (using the Bohdan weighing station) and labeled 20 mL vials, and the resin was washed with 4M ammonium hydroxide in methanol (4 2 mL) and tetrahydrofuran (2 2 mL), gravity elution. Positive nitrogen pressure was applied after the final elution (needle through a tight-fitting septum). Solvent was removed under vacuum with centrifugation to prevent bumping (Genevac apparatus) and the masses were recorded (Bohdan). 9. Hydrochloric acid (4N) in dioxane (excess) was added and they were capped and shaken at ambient temperature overnight. Solvent was removed again under vacuum with centrifugation, and masses were recorded (using the Bohdan weighing station). 10. Further purification was achieved through preparative HPLC separation, and samples with >80% purity were reevaluated for CNS binding activity as the formate salts.

Examples 180-239 The compounds of Examples 180-239 were prepared using the following general procedure and the purification technique noted. The appropriate aryl amine (0.29 mmol) was added to a 20 mL scintillation vial followed by the addition of a stock solution of the appropriate dichloroazepinoindole acid (5 mL, 0.053 M in THF). Next, a stock solution of EEDQ (3 mL, 0.097 M in THF) was added to each vial. The vials were capped, placed in a J-KEM ® heater block attached to a Lab-Line ® orbit shaker and shaken (250 RPM) at 40 °C overnight. A subset of the reactions was monitored by HPLC. After all the starting acid was consumed in these reactions, MeOH (3 mL) and Dowex ® 50WX2-400 ion-exchange resin (0.75 g) was added to each vial. The reactions were then shaken (300 RPM) at 40 °C until the product was on the resin, based on HPLC monitoring. The vials were cooled to rt and transferred with 2 x 5 mL of CH2Cl 2 /MeOH (3:1) to disposable fritted syringe barrels on a syringe washing station. The resin was then rinsed with 2 x 5 mL of each of the following: pyridine/MeOH (3:7), CH 2 C1 2 , and MeOH. The syringe barrels were then transferred to a vacuum manifold and the product was eluted off the resin into 40 mL scintillation vials with 5 x 5 mL of MeOH/NH OH (3:1). Three different methods were used to isolate products. Method A consisted of removing the solvent in the vacuum oven overnight at 47 °C. Method B involved blowing the solvent down under nitrogen and then further drying in the vacuum oven overnight at 47 °C. Method C consisted of filtering the precipitate that formed upon being blown down under nitrogen. The products were then evaluated by HPLC and MS or LC/MS.

Examples 252-307 Using the following general procedure the compounds of Examples 251- 306 were prepared. The appropriate aryl alcohol (0.50 mmol) was added to a 20 mL scintillation vial followed by the addition of a stock solution of the appropriate dichloroazepinoindole alcohol (0.10 g, 0.25 mmol) and PPh 3 (99 mg, 0.38 mmol) in THF (5 mL). Next, a stock solution of DBAD (87 mg, 0.38 mmol) in THF (3 mL) was added to each vial. The vials were capped, placed in a J-KEM ® heater block attached to a Lab-Line ® orbit shaker and shaken (250 RPM) at 40 °C overnight. A subset of the reactions was monitored by LC/MS. After all the starting alcohol was consumed in these reactions, MeOH (3 mL) and Dowex ® 50WX2-400 ion-exchange resin (0.75 g) was added to each vial. The reactions were then shaken (300 RPM) at 40 °C until the product was on the resin, based on LC/MS monitoring. The vials were cooled to rt and transferred with 2 x 5 mL of CH 2 Cl 2 /MeOH (3: 1) to disposable fritted syringe barrels on a syringe washing station. The resin was then rinsed with 3 x 10 mL of pyridine/MeOH (3:7), 1 x 10 mL of CH 2 C1 2 , and 3 x 10 mL of MeOH. The syringe barrels were then transferred to a vacuum manifold and the product was eluted off the resin with a total of 10 x 5 mL of MeOH/NH 4 OH (3: 1) into two 40 mL scintillation vials for each compound. The vials were blown down under nitrogen and followed by further drying in the vacuum oven overnight at 47 °C to give product. The products were evaluated by HPLC and MS or LC/MS.
