FIELD OF THE INVENTION
The present invention is directed to certain novel compounds represented by structural Formula (D) 




or pharmaceutically acceptable salt forms thereof, wherein R1, R5, R6, R7, R8, R9, X, b, k, and n, and the dashed line are described herein. The invention is also concerned with pharmaceutical formulations comprising these novel compounds as active ingredients and the use of the novel compounds and their formulations in the treatment of certain disorders. The compounds of this invention are serotonin agonists and antagonists and are useful in the control or prevention of central nervous system disorders including obesity, anxiety, depression, psychosis, schizophrenia, sleep disorders, sexual disorders, migraine, conditions associated with cephalic pain, social phobias, and gastrointestinal disorders such as dysfunction of the gastrointestinal tract motility.

BACKGROUND OF THE INVENTION
There exists a substantial correlation for the relationship between 5-HT2 receptor modulation and a variety of diseases and therapies. To date, three subtypes of the 5-M receptor class have been identified, 5-HT2A, 5-HT2B, and 5-HT2C. Prior to the early 1990's the 5-HT2C and 5-HT2A receptors were referred to as 5-HT1C and 5-HT2, respectively.
The agonism or antagonism of 5-HT2 receptors, either selectively or nonselectively, has been associated with the treatment of various central nervous system (CNS) disorders. Ligands possessing affinity for the 5-HT2 receptors have been shown to have numerous physiological and behavioral effects (Trends in Pharmacological Sciences, 11, 181, 1990). In the recent past the contribution of serotonergic activity to the mode of action of antidepressant drugs has been well documented. Compounds that increase the overall basal tone of serotonin in the CNS have been successfully developed as antidepressants. The serotonin selective reuptake inhibitors (SSRI) function by increasing the amount of serotonin present in the nerve synapse. These breakthrough treatments, however, are not without side effects and suffer from delayed onset of action (Leonard, J. Clin. Psychiatry, 54(suppl), 3, 1993). Due to the mechanism of action of the SSRIs, they effect the activity of a number of serotonin receptor subtypes. This non-specific modulation of the serotonin family of receptors most likely plays a significant role in the side effect profile. In addition, these compounds often have a high affinity for a number of the serotonin receptors as well as a multitude of other monoamine neurotransmitters and nuisance receptors. Removing some of the receptor cross reactivity would allow for the examination and possible development of potent therapeutic ligands with an improved side effect profile.
There is ample evidence to support the role of selective 5-HT2 receptor ligands in a number of disease therapies. Modulation of 5-HT2 receptors has been associated with the treatment of schizophrenia and psychoses (Ugedo, L., et. al., Psychopharmacology, 98, 45, 1989). Mood, behavior and hallucinogenesis can be affected by 5-HT2 receptors in the limbic system and cerebral cortex. 5-HT2 receptor modulation in the hypothalamus can influence appetite, thermoregulation, sleep, sexual behavior, motor activity, and neuroendocrine function (Hartig, P., et. al., Annals New York Academy of Science, 149, 159). There is also evidence indicating that 5-HT2 receptors mediate hypoactivity, effect feeding in rats, and mediate penile erections (Pyschopharmacology, 101, 57, 1990).
Compounds exhibiting selectivity for the 5-HT2B receptor are useful in treating conditions such as tachygastria, hypermotility associated with irritable bowel disorder, constipation, dyspepsia, and other peripherally mediated conditions.
5-HT2A antagonists have been shown to be effective in the treatment of schizophrenia, anxiety, depression, and migraines (Koek, W., Neuroscience and Behavioral reviews, 16, 95, 1996). Aside from the beneficial antipsychotic effects, classical neuroleptic are frequently responsible for eliciting acute extrapyramidal side effects and neuroendocrine disturbances. These compounds generally possess signifcant dopamine D2 receptor affinity (as well as other nuisance receptor affinity) which frequently is associated with extra pyramidal symptoms and tardive dyskinesia, thus detracting from their efficacy as front line treatments in schizophrenia and related disorders. Compounds possessing a more favorable selectivity profile would represent a possible improvement for the treatment of CNS disorders.
U.S. Pat. Nos. 3,914,421; 4,013,652; 4,115,577; 4,183,936; and 4,238,607 disclose pyridopyrrolobenz-heterocycles of formula: 




where X is O, S, S(═O), or SO2; n is 0 or 1; m is 0 or 1; R and R1 are various carbon substituents, and Z is a monosubstituent of H, methyl, or chloro.

U.S. Pat. No. 4,219,550 discloses pyridopyrrolo-benzheterocycles of formula: 




where X is O or S; R1 is C1-4 alkyl or cyclopropyl; R2 is H, CH3, OCH3, Cl, Br, F, or CF3; and (A) is —CH2—, —CH(CH3)—, or —CH2CH2—.

None of the above references suggest or disclose the compounds of the present invention.
There remains a need to discover new compounds useful as serotonin agonists and antagonists which are useful in the control or prevention of central nervous system disorders. As such, the present invention discloses novel compounds which are of low molecular weight, useful as serotonin agonists and antagonists, and provide good in vitro potency.
SUMMARY OF THE INVENTION
One object of the present invention is to provide novel compounds which are useful as agonists or antagonists of 5-HT2 receptors, more specifically 5-HT2A and 5-HT2C receptors, or pharmaceutically acceptable salts or prodrugs thereof.
It is another object of the present invention to provide pharmaceutical compositions comprising a pharmaceutically acceptable carrier and a therapeutically effective amount of at least one of the compounds of the present invention or a pharmaceutically acceptable salt or prodrug form thereof.
It is another object of the present invention to provide a method for treating central nervous system disorders including obesity, anxiety, depression, psychosis, schizophrenia, sleep and sexual disorders, migraine and other conditions associated with cephalic pain, social phobias, and gastrointestinal disorders such as dysfunction of the gastrointestinal tract motility comprising administering to a host in need of such treatment a therapeutically effective amount of at least one of the compounds of the present invention or a pharmaceutically acceptable salt or prodrug form thereof. More specifically, the present invention provides a method for treating obesity anxiety, depression, or schizophrenia.
These and other objects, which will become apparent during the following detailed description, have been achieved by the inventors' discovery that compounds of Formula (1): 




    
    
        or pharmaceutically acceptable salt or prodrug forms thereof, wherein R1, R5, R6, R7, R8, R9, X, b, k, and n are defined below, are effective agonists or antagonists of 5-HT2 receptors.

Definitions
The compounds herein described may have asymmetric centers. Compounds of the present invention containing an asymmetrically substituted atom may be isolated in optically active or racemic forms. It is well known in the art how to prepare optically active forms, such as by resolution of racemic forms or by synthesis from optically active starting materials. Many geometric isomers of olefins, C═N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present invention are described and may be isolated as a mixture of isomers or as separated isomeric forms. All chiral, diastereomeric, racemic forms and all geometric isomeric forms of a structure are intended, unless the specific stereochemistry or isomeric form is specifically indicated.
The numbering of the tetracyclic ring-system present in the compounds of Formula (I), as defined by nomenclature known to one skilled in the art, is shown for two examples in Formula (I′), when k is 1 and n is 1; and in Formula (I′′), when k is 1 and n is 2: 




The tetracyclic ring-system present in compounds of Formula (I) occur as “cis” or “trans” isomers when the carbon-carbon bond b in Formula (I) is a single bond. As such, the terms “cis” and “trans”, in conjunction with the tetracyclic ring structure, refer to the configuration of hydrogen atoms on carbon atoms 8a and 12a in Formula (I′) or, for example, on carbon atoms 9a and 13a in Formula (I′′), above. When both hydrogens are on the same side of the mean plane determined by the octahydro tetracyclic moiety then the configuration is designated “cis”, if not, the configuration is designated “trans”. It is understood that the above example is for demonstrative purposes only and not intended to limit the scope of the tetracyclic ring-system present in compounds of Formula (I). As such, it is understood that one skilled in the art of organic chemistry can apply the above numbering system to other values of k, m, and n in the scope of compounds of Formula (I) to determine the appropriate numbering. Additional Examples of the numbering of the tetracyclic ring-system are further provided below in the synthetic Examples. Lastly, it is understood that the use of “cis” or “trans” in the identification of the tetracyclic ring-system is not meant to construe the configuration of any other cis or trans geometric isomer in the molecule, for example, cis or trans butene.

The term “substituted,” as used herein, means that any one or more hydrogens 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. When a substituent is keto (i.e., ═O), then 2 hydrogens on the atom are replaced.
When any variable (e.g., R2, R11, R33, R41, R42, etc.) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-2 R2, then said group may optionally be substituted with up to two R2 groups and R2 at each occurrence is selected independently from the definition of R2. Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.
When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such substituent. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

The compounds of the present invention can be prepared in a number of ways well known to one skilled in the art of organic synthesis. The compounds of the present invention can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or variations thereon as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. All references cited herein are hereby incorporated in their entirety herein by reference.
The novel compounds of this invention may be prepared using the reactions and techniques described in this section. The reactions are performed in solvents appropriate to the reagents and materials employed and are suitable for the transformations being effected. Also, in the description of the synthetic methods described below, it is to be understood that all proposed reaction conditions, including choice of solvent, reaction atmosphere, reaction temperature, duration of the experiment and workup procedures, are chosen to be the conditions standard for that reaction, which should be readily recognized by one skilled in the art. It is understood by one skilled in the art of organic synthesis that the functionality present on various portions of the molecule must be compatible with the reagents and reactions proposed. Such restrictions to the substituents which are compatible with the reaction conditions will be readily apparent to one skilled in the art and alternate methods must then be used.
The preparation of compounds of Formula (I) of the present invention may be carried out in a convergent or sequential synthetic manner. Detailed synthetic preparations of the compounds of Formula (I) are shown in the following reaction schemes. The skills required in preparation and purification of the compounds of Formula (I) and the intermediates leading to these compounds are known to those in the art. Purification procedures include, but are not limited to, normal or reverse phase chromatography, crystallization, and distillation.
Several methods for the preparation of the compounds of the present invention are illustrated in the schemes and examples shown below. The substitutions are as described and defined above.
Compounds of Formula (I) of this invention may be prepared as shown in Scheme 1. Thus, preparation of an aryl hydrazine (III) is accomplished, for example, by treatment of a corresponding substituted aniline (II) with NaNO2 followed by reduction of the N-nitroso intermediate with a reducing agent such as LAH or zinc and an organic acid, such as acetic acid or trifluoroacetic acid at low temperature. Assembly of the core tetracyclic intermediate indole (V) is accomplished by Fischer indole cyclization of the aryl hydrazine and a suitably substituted ketone (i.e. (IV)) by methods described by, but not limited to, R. J. Sundberg, “Indoles, Best Synthetic Methods” 1996, Academic Press, San Diego, Calif. For example, treatment of the aryl hydrazine (III) as the free base or the corresponding mineral acid salt with the ketone (IV) (R1=H, Bn, CBZ, CO2Et, etc) in an alcoholic solvent in the presence of mineral acid affords the indoles (V) as the free bases (after treatment with aq. NaOH). Reduction of the indoles to the corresponding cis-or trans substituted dihydroindoles is accomplished by, for example, treatment with hydrogen in the presence of a catalyst such as platinum oxide or palladium on carbon, or with a metal such as zinc and a mineral acid such as hydrochloric acid, or with sodium and liquid ammonia, or with borane-amine complex such as borane-triethylamine in tetrahydofuran, or preferably by treatment with triethylsilane or NaCNBH3 in an acid such as acetic or trifluoroacetic acid.
The corresponding enantiomers can be isolated by separation of the racemic mixture of (I) on a chiral stationary phase column utilizing normal or reverse phase HPLC techniques, the details of which are described in the examples. Alternatively, a diastereomeric mixture of (I) can be prepared by treatment of (I, R1=H) with an appropriate chiral acid (or suitably activated derivative), for example dibenzoyl tartrate or the like (see, for example, Kinbara, K., et. al., J Chem. Soc., Perkin Trans. 2, 1996, 2615; and Tomori, H., et. al., Bull. Chem. Soc. Jpn., 1996, 3581). The diastereomers would then be separated by traditional techniques (i.e. silica chromatography, crystallization, HPLC, etc) followed by removal of the chiral auxiliary to afford enantiomerically pure (I). 




In the cases where the carboline nitrogen has been protected (VI) (i.e. R1=Boc, Bn, CBZ, CO2R), it may be removed under a variety of conditions as described in Greene, T. W., Wuts, P. G. W., “Protective Groups in Organic Synthesis, 2nd Edition”, John Wiley and Sons, Inc., New York, pages 309-405, 1991. The free secondary amine could then be alkylated, for example, by treatment with a suitably substituted alkyl halide (R1Cl, or R1I) and a base to afford additional compounds of Formula (I), as described, for example, by Glennon, R. A., et. al., Med Chem. Res., 1996, 197. 




Alternatively, compounds of Formula (I) where X=O or S can be prepared as described in Scheme 2. The ortho-nitro compounds (VII) are readily available by standard procedures known to those skilled in the art. For example, where Z=Br, compounds (VII) are available by radical bromination of an appropriate ortho-nitroalkylphenyl compound. Where Z=OMs, compounds (VII) are available by reduction of an appropriate ortho-nitrophenylketone compound with sodium borohydride and conversion to the mesylate with methanesulfonyl chloride and base. Alternatively, compounds (VII) are available by addition of an appropriate alkyl Grignard or alkyllithium reagent to an appropriate ortho-nitrobenzaldehyde followed by subsequent conversion of the alcohol to a mesylate or other leaving group. Treatment of (VII) with a nucleophilic alkyl halide (X=OH, SH (VIII)) and a suitable base followed by subsequent reduction of the corresponding nitroaryl derivative affords the aniline (IX). The reduction may be accomplished with a variety of reducing agents, for example, SnCl2, LAH, NaBH4, N2H4, etc. or with hydrogen in the presence of a suitable catalyst, such as palladium on carbon, or platinum oxide, etc., (see Hudlicky, M., “Reductions in Organic Chemistry”, Ellis Horwood, Ltd., Chichester, UK, 1984). Formation of the aryl hydrazine (X) may be accomplished as described previously in Scheme 1 or more directly by treatment of the aniline (IX) with aq. hydrochloric acid, stannous chloride and NaNO2 at room temperature (see, Buck, J. S., Ide, W. S., Org. Syn., Coll. Vol., 2, 1943, 130). This primary aryl hydrazine (X) can then be cyclized under Fischer indole cyclization conditions as detailed above for compound (V), to afford the indole (XI) as the corresponding salt. Treatment of the indole (XI) with a base such potassium hydroxide or potassium t-butoxide in a solvent such as DME or THF affords the tetracyclic indole intermediates (V). These indoles can also be reduced to the corresponding cis-or trans indolines (I) as described previously in Scheme 1.
Compounds of Formula (1) where X=NR10 can alternatively be prepared as described in Scheme 3. Treatment of hydrazino benzoic acids (XII), which are either commercially available or are readily available by standard procedures known to those skilled in the art, under the Fischer indolization conditions described earlier affords indoles (XIII). These indoles can be reduced to the corresponding cis-or trans indolines (XIV) as described previously. Amide bond formation between the carboxylic acid and an appropriate haloalkyl amine (XV) can be accomplished under a variety of amide bond forming conditions, such as with a coupling agent such as dicyclohexylcarbodiimide or carbonyl diimidazole, to give the amides (XVI). Ring closure can be accomplished by treating (XVI) with a base such as potassium hydroxide or potassium tert-butoxide with heating in the presence of potassium iodide to give a tetracyclic amide. Reduction of the amide carbonyl with a suitable reducing agent, such as borane tetrahydrofuran complex or lithium aluminum hydride, affords the tetracyclic amine (XVII). Introduction of the R10 substituent can be readily accomplished by standard procedures, affording compounds (I). In the cases where the carboline nitrogen has been protected (XVII) (i.e. R1=Boc, Bn, CBZ, CO2R), it may be removed under a variety of conditions as described previously. The free secondary amine could then be alkylated, for example, by treatment with a suitably substituted alkyl halide (R1Cl, or R1I) and a base to afford additional compounds of Formula (I), as described in Scheme 1. 




Preparation of the aniline precursors (II) to the Fischer indole cyclizations is described in the following Schemes. The preparation of compounds (II) where X=S is shown in Scheme 4. Compounds (VII) can be readily displaced with a variety of mercaptoester or acid derivatives (XIX) to afford (XX). Reduction of the nitro group by tin chloride or a variety of other well known reduction methods affords an aniline intermediate. Ring-closing condensation can occur spontaneously or under heating conditions to afford a lactam, which can be reduced with borane-tetrahydrofuran complex or LAH to give the aniline intermediates (II). Alternatively, compounds (VII) can be converted by a variety of procedures into the corresponding benzylthiol derivatives, such as by displacement with thiourea and subsequent hydrolysis. Reaction of the intermediate sulfides with chloroester and acid derivatives (XXI) affords (XX), which can be converted as previously described into the aniline intermediates (II). 




Alternatively, the anilines (II) where X=S can be prepared as described in Scheme 5. Compounds (XXII) are commercially available or are readily available by procedures described for compounds (VII) or by other procedures known to those skilled in the art. Displacement of the Z group with mercaptoesters or acids (XIX) affords compounds (XXIII). Hydrolysis of the ester forms an acid which, when treated under Friedel-Crafts acylation conditions (see Ed. G. A. Olah, “Friedel-Crafts and Related Reactions”, J. Wiley and Sons, New York, 1964, Vol 3, Pts 1 and 2 or Chem. Rev., 1955, 229, or Olah, G. A., “Friedel-Crafts Chemistry”, Wiley Interscience, New York, 1973, for varying conditions and protocols), i.e. strong Lewis acids (AlCl3, FeCl3, etc.), affords the cyclic ketones (XXIV). Incorporation of the nitrogen functionality can be accomplished in several ways. For example, Schmidt rearrangement (as described by Smith, P. A. S., J. Am. Chem. Soc., 1948, 320) is effected by treatment of the carbonyl derivative (XXIV) with NaN3 and methanesulfonic acid to afford the bicyclic lactam (XXV). Alternatively, this transformation may be carried out under Hoffmann rearrangement protocol (see, for example, Dike, S. Y., et. al., Bioorg. Med. Chen Lett., 1991, 383), by initial formation of the oxime derivative of (XXIV) by treatment with hydroxylamine hydrochloride. Subsequent rearrangement to the lactam is efficiently accomplished by heating in polyphosphoric acid to afford the lactam (XXV). Reduction of the lactam (XXV) can be accomplished with a variety of reducing agents, for example, borane-THF complex, LAH and the like to afford the aniline intermediates (II). One skilled in the art will recognize that the intermediates (XXII) are readily available by other methods, for example by following the sequence described in the bottom of Scheme 




Preparation of the aniline precursors (II) to the Fischer indole cyclizations where X=O is shown in Scheme 6. 2-Aminobenzyl alcohols (XXVI) are either commercially available or are readily available by standard synthetic methods, such as by the reduction of an appropriate ketone or aldehyde or by addition of an appropriate Grignard or alkyllithium reagent to an appropriate aldehyde, whereby the amino functionality can be suitably protected or can be subsequently derived from reduction of a nitro group. N-acylation of (XXVI) with a chloroalkyl acid chloride such as (XXVII) in the presence of a base such as triethylamine, or with an appropriate chloroalkyl carboxylic acid under a variety of amide bond coupling procedures, affords an amide intermediate which can by be cyclized to the lactams (XXVIII) by treatment with a base such as sodium ethoxide. Reduction of the lactam carbonyl can be readily accomplished with a variety of reducing agents, such as LAH or borane-THF complex, as described earlier. This reduction affords the anilines (II) where X=O. Alternatively, anilines (II) where X=O can be prepared by displacing the Z group in (VII) with an appropriate hydroxy ester (XXIX) to afford (XXX), in an analogous fashion as described in Scheme 4. Also, the same compounds (XXX) are available from the readily available benzyl alcohols (XXXI) by alkylation with chloroalkyl esters (XXXII) in the presence of a base such as sodium hydride. Reduction of the nitro group of (XXX) with, for example, SnCl2 followed by ring-closing condensation as described in Scheme 4 affords the lactam intermediate (XXVIII). Reduction of the lactam as described previously affords the anilines (II) where X=O. 




The preparation of aniline intermediates (II) where X=NR10 is accomplished as described in Scheme 7. N-Acylation of diamines (XXXIII), readily available by standard procedures known to those skilled in the art with chloroalkyl acid chlorides (XXVII) in the presence of a base such as triethylamine affords an amide. This amide can also be formed by coupling an appropriate chloroalkyl carboxylic acid with (XXXIII) under standard amide bond coupling conditions. Heating the amide intermediate, possibly in the presence of a base, affords the lactams (XXXIV). Reduction of the lactam with LAH or borane followed by N-alkylation of the more nucleophilic ring nitrogen affords anilines (II) where X=NR10. The group R10 can also be a suitable protecting group, such as CBZ, CO2R, etc., as long as it is compatible with the Fischer indole cyclization conditions. Subsequent deprotection and N-alkylation would provide the N—R10 groups found in compounds of Formula (I).
Alternatively, N-alkylation of amino esters (XXXV) with compounds (VII) in the presence of a suitable base such as triethylamine or potassium carbonate would afford (XXXVI). Compounds (XXXVI) would also be available by reductive amination (NaCNBH3, methanol, acetic acid) of an appropriate ortho-nitrobenzaldehyde with aminoesters (XXXV). Nitro group reduction, ring-closing condensation, amide reduction and N-alkylation with R10I would then afford anilines (II) where X=NR10.
Alternatively, the anthranilic acids (XXXVII) can be coupled with an appropriate chloroalkylamine (XV) under a variety of amide bond forming conditions to afford the amides (XXXVIII). Nitro group reduction as described previously, followed by intramolecular N-alkylation, induced by heat and/or treatment with a suitable base such as triethylamine or potassium hydroxide, would afford a lactam intermediate. Reduction with borane or LAH as described previously, followed by N-alkylation with R10I would then afford anilines (II) where X=NR10. 




The preparation of compounds of Formula (I) with additional diversity of functionalization of the aromatic A ring of the tetracycle is shown in the following Schemes. As shown in Scheme 8, bromination of the indolines (I, R8=H) when the amine is protected, for example, with the Boc or CBZ protecting groups, with, for example, NBS in DMF affords the R8 brominated derivatives (XXXIX). These activated aryl derivatives (XXXIX) act as excellent counterparts for a number of important synthetic transformations.
For example, biaryl coupling is accomplished under Suzuki coupling protocol. For a review and leading references of palladium catalyzed cross coupling reactions, see Miyaura, N., Suzuki, A., Chem. Rev., 1995, 2457. One such procedure entails treatment of the aryl bromide (XXX) with a functionalized aryl boronic acid (L) in the presence of a catalytic Pd(0) species, such as Pd(PPh3)4, Pd(PPh3)2Cl2, Pd(OAc)2, Pd2(dba)3 and a suitable ligand such as PPh3, AsPh3, etc., or other such Pd(0) catalyst, and a base such as Na2CO3, Ba(OH)2 or Et3N in a suitable solvent such as DMF, toluene, THF, DME or the like, to afford the indolines (XLI). 




Alternatively formation of the indole boronic ester from the bromine derivative (XXXIX) (i.e. (I, R8=B(OR)2) would allow for greater diversity in the subsequent coupling of this indole boronic acid with commercially available haloaromatic derivatives in a similar Suzuki coupling strategy as described above to afford the indolines (XLI). One such procedure is shown in Scheme 9. Treatment of bromides (XXXIX) with a palladium catalyst such as Pd(PPh3)4 or Pd(PPh3)2Cl2 and a suitable base, a preferred one being potassium acetate, in the presence of diboron pinacol ester (XLII) affords the aryl boronic ester (XLIII). This boronic ester can undergo Suzuki coupling directly with a wide variety of commercially available aryl bromides (XLIV) under typical Suzuki conditions as described in Scheme 8 to afford the indolines (XLI). 




Similarly, biaryl coupling of the bromine derivatives (XLV), readily obtained by the synthetic sequence exemplified in Scheme 2, (starting with the suitably functionalized ortho-nitro compounds (VII)), is shown in Scheme 10. This approach allows for the preparation of biaryl indoles as well as the corresponding indoline derivatives. Protection of the amine functionality must be carried out if R1=H (see Greene et. al for protections of amines). This is readily accomplished, for example, by treatment of bromo derivatives (XLV) with (Boc)2O in aqueous sodium hydroxide and dioxane. Subsequent Suzuki coupling with a variety of aryl boronic acids is carried out as described above in Scheme 8, to afford the biaryl adducts (XLVI). This protocol is amenable to R7, R8, and R9 bromide, iodide, triflates, and/or diazo derivatives (see Miyaura, N., Suzuki, A., Chem. Rev., 1995, 2457, for a review of aryl couplings). 




In addition, there exists a wide range of procedures and protocols for functionalizing haloaromatics, aryldiazonium and aryltriflate compounds. These procedures are well known by those in the art and described, for example, by Stanforth, S. P., Tetrahedron, 1998, 263; Buchwald, S. L., et. al., J. Am. Chem. Soc., 1998, 9722; Stille, J. K., et. al., J. Am. Chem. Soc., 1984, 7500. Among these procedures are biaryl couplings, alkylations, acylations, aminations, and amidations. The power of palladium catalyzed functionalization of aromatic cores has been 110 explored in depth in the last decade. An excellent review of this field can be found in J. Tsuji, “Palladium Reagents and Catalysts, Innovations in Organic Synthesis”, J. Wiley and Sons, New York, 1995.
One such example is described in Scheme 11, where the aromatic A ring of Formula (I) is substituted with an arylamino group. Treatment of bromide (XXXIX) with benzophenone imine in the presence of a palladium (0) catalyst, such as Pd2(dba)3, Pd(PPh3)4 or Pd(PPh3)2Cl2, and a suitable ligand such as BINAP or PPh3, and a base such as NaOtBu in a suitable solvent such as DMF, toluene, THF, DME or the like, affords an imine in which nitrogen is attached to the aromatic ring. Hydrolysis of this imine, for example with hydroxylamine and sodium acetate in methanol, affords the aniline (XLVI). This aniline (XLVI) can be treated with a wide variety of commercially available aryl bromides (XLIV) in the presence of a palladium (0) catalyst, such as Pd2(dba)3, Pd(PPh3)4 or Pd(PPh3)2Cl2, and a suitable ligand such as BINAP or PPh3, and a base such as NaOtBu in a suitable solvent such as DMF, toluene, THF, DME or the like, to afford the biaryl anilines (XLVII). In analogy with Scheme 10, the chemistry described in Scheme 11 can also be applied to analogs of (XXIX) where the R7 or R9 groups are Br, I, OTf, etc., to afford analogs of (XLVII) where the arylamino group is on the R7 or R9 position. 




Another example is shown in Scheme 12. Treatment of the anilines (XLVI) with an appropriate benzaldehyde (XLVII) in the presence of a suitable reducing agent such as sodium triacetoxyborohydride or sodium cyanoborohydride and generally under mildly acidic conditions, such as in the presence of acetic acid, in a suitable solvent such as 1,2-dichloroethane, THF, methanol or acetonitrile, affords the benzylamine analogs (XLIX). An alternate method for preparing benzylamines (XLIX) or □-substituted benzylamines (LI) proceeds from bromides (XXXIX). Treatment of bromide (XXXIX) with benzylamines (L), which can be chiral if R10 is an appropriate group, such as alkyl, in the presence of a palladium (0) catalyst, such as Pd2(dba)3, Pd(PPh3)4 or Pd(PPh3)2C2, and a suitable ligand such as BINAP or PPh3, and a base such as NaOtBu or Na2CO3 in a suitable solvent such as DMF, toluene, THF, DME or the like, affords the benzylamines (LI). In analogy with previous schemes, the chemistry described in Scheme 12 can also be applied to analogs of (XLVI) or (KNOX) where the R7 or R9 groups are NH2, Br, 1, OTf, etc., to afford analogs of (XLIX) or (LI) where the benzylamino group is on the R7 or R9 position. 




Another example is shown in Scheme 13. Treating bromides (XXXIX) with an appropriate benzylic zinc reagent (LII), which can be generated from the corresponding benzyl halide, in the presence of a palladium (O) catalyst such as Pd(PPh3)4, Pd(PPh3)2C2, or Pd2(dba)3, and with or without a copper (I) salt, affords the derivatives (LIII) where R8 is a benzyl group (see Knochel, P., et. al. Chem. Rev. 1993, 93, 2117; and Weichert, A., et. al. Syn. Lett. 1996, 473). This chemistry can also be extended to include a variety of alkylzinc and cycloalkylzinc reagents, which are available from the corresponding alkyl halides and cycloalkyl halides. In analogy with previous schemes, the chemistry described in Scheme 13 can also be applied to analogs of (XXXIX) where the R7 or R9 groups are Br, I, OTf, etc., to afford analogs of (LIII) where the benzyl or alkyl or cycloalkyl group is on the R7 or R9 position. 




Another example is shown in Scheme 14. Compounds (XXXIX), where X is bromo or preferably iodo, can be treated with various phenols (LIV) in the presence of a base such as Cs2CO3 and a copper catalyst such as CuPF6(CH3CN)4 at elevated temperature to afford biaryl ethers (LV) (see Sawyer, J. S. Tetrahedron 2000, 56, 5045). In analogy with previous schemes the chemistry described in Scheme 14 can also be applied to analogs of (XXXIX) where the R7 or R9 groups are Br, 1, OTf, etc., to afford analogs of (LV) where the aryloxy group is on the R7 or R9 position. 




The compounds of Formula (I) with substituted R1 sidechains can be prepared as described in Scheme 15. Alkylation of the indole or indoline derivatives (I, R1=H) with a haloalkyl ester, such as ClCH2(CH2)pCO2Me, in the presence of NaI or KI and a base such as K2CO3, Na2CO3 or the like, in dioxane or THF or other such solvent while heating (see Glennon, R. A., et. al., Med Chem. Res., 1996, 197) affords the R1 alkylated esters. Subsequent formation of the activated amides ((LVI)) is accomplished by treatment of the ester with N,O-dimethylhydroxylamine hydrochloride and a Lewis acid such as trimethylaluminum or triethylaluminum in toluene (see, for example, Golec, J. M. C., et. al., Tetrahedron, 1994, 809) at 0° C. Treatment of the amide (LVI) with a variety of organometallic agents, such as Grignard reagents R1aMgBr, alkyl and aryl lithium reagents etc. (see Sibi, M. P., et. al., Tetrahedron Lett., 1992, 1941; and more generally House, H. O., Modern Synthetic Reactions, W. A. Benjamin, Inc., Menlo Park, Calif., 1972), in a suitable solvent such as THF, ether, etc. at low temperatures affords the substituted ketones (LVII). 




Preparation of compounds of Formula (I) where m=0, k=1 is outlined in Scheme 16 and described here. Fischer indole cyclization of the previously described hydrazine (III) with a known protected 2,3-dioxopyrrolidine (LVIII) (Carlson, E. H., et. al., J. Org. Chem., 1956, 1087) under a variety of typical cyclization conditions affords the tetracyclic indole (LIX). The reduction may be accomplished with a variety of reducing agents, for example, LAH, DIBAL, etc., to yield the pyrrole fused indole (LX). This derivative can then be deprotected and subsequently alkylated as described previously (see Greene, T. W., Wuts, P. G. W., “Protective Groups in Organic Synthesis, 2nd Edition”, John Wiley and Sons, Inc., New York, 1991, and Scheme 1), to give the R1 alkylated indole analogs (LXI). Alternatively, reduction of the indole (LX) to the indoline, as described previously (see Scheme 1), followed by deprotection of the benzyl group to give (LXII) and N-alkylation gives access to the corresponding R1 alkylated indoline derivatives (LXIII). All the previously described methods to functionalize the aromatic ring, and to afford derivatives of varying R1 sidechains are applicable to these cores.

A 2-L round-bottom flask was charged with 1,5-dihydro-4,1-benzothiazepin-2(3H)-one (22.5 g, 126 mmol) followed by borane-tetrahydrofuran complex (1 M in THF, 629 mmol, 625 mL) at ambient temperature. The mixture was brought to reflux for 4 hours. The mixture was cooled to 0° C. and 100 mL of water was carefully added dropwise, resulting in the evolution of a large volume of gas. The mixture was then heated under reflux for 10 min, cooled to room temperature and extracted with ether (3×300 mL).

A portion of the later eluting (7bR,11aS) isomer was dissolved in CH2Cl2 (5 ml) at 25° C. and there was added trifluoroacetic acid (1 mL).

Utility
The compounds of the present invention have therapeutic utility for illnesses or disorders involving the neurotransmitter serotonin (5-hydroxy tryptamine or 5-HT) and either agonism or antagonism of 5-HT2 receptors, as demonstrated by the assays described below. Therapeutic utility for these illnesses or disorders could involve numerous biological processes affected by serotonin including, but not limited to, appetite, mood, sleep, sexual activity, and arterial constriction. These biological processes may also be important to numerous central nervous system (CNS) disorders including those related to the affective disorders of depression, anxiety, psychosis, and schizophrenia, as well as, disorders of food intake such as anorexia, bulemia, and obesity. The compounds of the present invention potentially have therapeutic utility in other conditions in which serotonin has been implicated, such as migraine, attention deficit disorder or attention deficit hyperactivity disorder, addictive behavior, and obsessive-compulsive disorder, as well as, conditions associated with cephalic pain, social phobias, and gastrointestinal disorders such as dysfunction of the gastrointestinal tract motility. Lastly, compounds of the present invention potentially have therapeutic utility in neurodegenerative diseases and traumatic conditions represented by the examples of Alzheimer's disease and brain/spinal cord trauma
The pharmacological analysis of each compound for either antogonism or agonism of at 5-HT2A and 5-HT2C receptors consisted of in vitro and in vivo studies. In vitro analyses included Ki determinations at 5-HT2A and 5-HT2C receptors and an assessment of functional (i.e., agonism or antagonism) activity at each receptor class by IP3 hydrolysis assays. Additional receptor assays were conducted to evaluate receptor specificity of 5-HT2A and 5-HT2C receptors over monoamine and nuisance receptors (e.g. histamine, dopamine, and muscarinic). A compound is considered active as a 5-HT2A antagonist or a 5-HT2C agonist if it has an IC50 value or a Ki value of less than about 50 micromolar; preferably less than about 0.1 micromolar; more preferably less than about 0.01 micromolar. Using the assays disclosed herein, compounds of the present invention have been shown to have an IC50 value of less than about 50 micromolar for 5-HT2A antagonism or 5-HT2C agonism.
In vivo assays assessed compound activity in a variety of behavioral paradigms including quipazine head twitch, acute and chronic feeding models, anxiety and depression models (learned-helplessness, elevated plus maze, Geller-Siefter, conditioned taste aversion, taste reactivity, satiety sequence). In aggregate, these models reflect activity as a 5-HT2A antagonist (quipazine head twitch; depression models) or 5-HT2C agonist (feeding models, anxiety models, depression models) and provide some indication as to bioavailability, metabolism and pharmacokinetics.
Radioligand binding experiments were conducted on recombinant human 5-HT2A and 5-HT2C receptors expressed in HEK293E cells. The affinities of compounds of the present invention to bind at these receptors is determined by their capacity to compete for [125I]-1-(2,5-dimethoxy-4-iodophenyl)-2-amino-propane (DOI) binding at the 5-HT2A or 5-HT2C. General references for binding assays include 1) Lucaites VL, Nelson DL, Wainscott DB, Baez M (1996) Receptor subtype and density determine the coupling repertoire of the 5-HT2 receptor subfamily.

Mol Pharmacol., 42(2): 328-35.
The functional properties of compounds (efficacy and potency) were determined in whole cells expressing 5-HT2A or 5-HT2C receptors by assessing their ability to stimulate or inhibit receptor-mediated phosphoinositol hydrolysis. The procedures used are described below.
In Vitro Binding Assays
Stable Expression of 5-HT2A and 5-HT2C Receptors in HEK293E Cells.
Stable cell lines were generated by transfecting 293EBNA cells with plasmids containing human 5-HT2A, 5-HT2B, or 5-HT2C (VNV edited isoform) cDNA using calcium phosphate. These plasmids also contained the cytomegalovirus (CMV) immediate early promoter to drive receptor expression and EBV oriP for their maintenance as an extrachromosomal element, and the hph gene from E. Coli to yield hygromycin B resistance (Horlick et al., 1997). Transfected cells were maintained in Dulbecco's Modified Eagle medium (DMEM) containing dialyzed 10% fetal bovine serum at 37° C. in a humid environment (5% CO2) for 10 days. The 5-HT2A cells were adapted to spinner culture for bulk processing whereas it was necessary to maintain the other lines as adherent cultures. On the day of harvest, cells were washed in phosphate-buffered saline (PBS), counted, and stored at −800C.
Membrane Preparation
On the day of assay, pellets of whole cells (containing approximately 1×108 cells) expressing the 5-HT2A or 5-HT2C receptor were thawed on ice and homogenized in 50 mM Tris HCl (pH 7.7) containing 1.0 mM EDTA using a Brinkman Polytron (PT-10, setting 6 for 10 sec). The homogenate was centrifuged at 48,000×g for 10 min and the resulting pellet washed twice by repeated homogenization and centrifugation steps. The final pellet was resuspended in tissue buffer and protein determinations were made by the bichichoninic acid (BCA) assay (Pierce Co., IL) using bovine serum albumin as the standard.
Radioligand Binding Assays for the 5-HT2A and 5-HT2C Receptors.
Radioligand binding studies were conducted to determine the binding affinities (KI values) of compounds for the human recombinant 5-HT2A, 5-HT2B, and 5-HT2C receptors (Fitzgerald et al., 1999). Assays were conducted in disposable polypropylene 96well plates (Costar Corp., Cambridge, Mass.) and were initiated by the addition of 5-HT2A, 5-HT2B, or 5-HT2C membrane homogenate in tissue buffer (10-30 (g/well) to assay buffer (50 mM Tris HCl, 0.5 mM EDTA, 10 mM pargyline, 10 mM MgSO4, 0.05% ascorbic acid, pH 7.5) containing [125I]DOI for the 5-HT2A and 5-HT2C receptors (0.3-0.5 nM, final) or [3H]LSD (2-2.5 nM, final) for the 5-HT2B receptor, with or without competing drug (i.e, newly synthesized chemical entity). For a typical competition experiment, a fixed concentration of radioligand was competed with duplicate concentrations of ligand (12 concentrations ranging from 10 picomolar to 10 micromolar). The reaction mixtures were incubated to equilibrium for 45 min at 37° C. and terminated by rapid filtration (cell harvester; Inotech Biosystems Inc., Lansing, Mich.) over GFF glass-fiber filters that had been pre-soaked in 0.3% polyethyleneimine. Filters were washed in ice-cold 50 mM Tris HCl buffer (pH 7.5) and then counted in a gamma counter for the 5-HT2A and 5-HT2C assays, or by liquid scintillation spectroscopy for the 5-HT2B assay.
Phosphoinositide Hydrolysis Studies.
The ability of newly synthesized compounds to stimulate phosphoinositide (PI) hydrolysis was monitored in whole cells using a variant (Egan et al., 1998) of a protocol described previously (Berridge et al., 1982). HEK293E cells expressing the human 5-HT2A, 5-HT2B, or 5-HT2C receptor were lifted with 0.5 mM EDTA and plated at a density of 100,000/well onto poly-D-lysine-coated 24-well plates (Biocoat; Becton Dickinson, Bedford, Mass.) in Dulbecco's modified Eagle's serum (DMEM; Gibco BRL) containing high glucose, 2 mM glutamine, 10% dialyzed fetal calf serum, 250 (g/ml hygromycin B, and 250(g/ml G418. Following a 2448 hr period, the growth media was removed and replaced with DMEM without fetal calf serum and inositol (Gibco BRL). The cells were then incubated with DMEM (without serum and inositol) containing a final concentration of 0.5 uCi/well myo-[3H]inositol for 16-18 hr. Following this incubation, the cells were washed with DMEM (without serum or inositol) containing 10 mM LiCl and 10 (M pargyline and then incubated for 30 min with the same media but now containing one of several test compounds. Reactions were terminated by aspirating the media and lysing the cells by freeze-thaw. [3H]phosphoinositides were extracted with chloroform/methanol (1:2 v/v), separated by anion exchange chromatography (Bio-Rad AGI-X8 resin), and counted by liquid scintillation spectroscopy as described previously (Egan et al., 1998).
Data Analyses
The equilibrium apparent dissociation constants (Ki's) from the competition experiments were calculated using an iterative nonlinear regression curve-fitting program (GraphPad Prism; San Diego, Calif.). For the PI hydrolysis experiments, EC50's were calculated using a one-site ‘pseudo’ Hill model: y=((Rmax−Rmin)/(1+R/EC50)nH))+Rmax where R=response (Deltagraph, Monterey, Calif.). Emax (maximal response) was derived from the fitted curve maxima (net IP stimulation) for each compound. Intrinsic activity (IA) was determined by expressing the Emax of a compound as a percentage of the Emax of 5-HT (IA=1.0).
In Vivo Experiments for Serotonergie Ligands.
Preclinical Efficacy, Potency, and Side Effect Liability.
a) Anti-Serotonin Efficacy.
Antagonism of Quipazine-Induced Head Twitch in Rat. Quipazine, an agonist at 5-HT receptors, produces a characteristic head twitch response in rats. 5-HT receptor antagonists effectively antagonize this 5-HT agonist-induced behavioral effect (Lucki et al., 1984). Accordingly, the quipazine-induced head twitch model in rat can function as an in vivo behavioral correlate to 5-HT receptor binding. Compounds are administered 30 minutes before behavioral testing (and 25 minutes before quipazine), and a dose-related antagonism of the quipazine response is determined.
b) Antipsychotic Efficacy.
Inhibition of the Conditioned Avoidance Response (CAR) in Rat. Rats are trained to consistently avoid (by climbing onto a pole suspended from the ceiling of the test chamber) an electric foot shock (0.75 mA) delivered to the grid floor of the testing chamber. All antipsychotic drugs effectively inhibit this conditioned avoidance response (Arnt, 1982). The ability of a compound to inhibit this response is used to determine the antipsychotic efficacy of potential drug candidates.
c) Extrapyramidal Side Effect Liability.
Induction of Catalepsy in Rat. Typical antipsychotic drugs produce extrapyramidal side effects (EPS) at clinically effective doses. The most widely accepted preclinical indicator of EPS liability in humans is a drug-induced catalepsy syndrome in rat (Costall and Naylor, 1975), a condition whereby the animal will remain immobile in an externally imposed posture (analogous to a catatonic stupor in humans). Rats are tested for induction of catalepsy in a dose-response test after oral administration of compounds.
d) CNS Penetration; In vivo Brain Receptor Occupancy.
In Vivo Binding. To determine the level of in vivo receptor occupancy, an in vivo receptor binding protocol is used. This procedure uses an appropriate radioligand to label the receptor of interest. For example, to measure both Dopamine D2 and 5-HT2A receptors in vivo, one can use 3H—N-methyl spiperone (3H —NMSP), (Frost, et. al. 1987) The procedure uses rats (or mice) fasted overnight. To measure the effects of compounds on the receptors of interest, compounds are dosed, usually p.o. for example in 2 microliters/gram body weight in 0.25% Methocel suspension. The radiolabeled compound (in this example, 3H—NMSP) is administered by i.v. tail vein injection (10 microcuries label/200 gram rat). Time course experiments are used to determine the optimal time of binding for both the radiolabeled and unlabeled compound. These optimal time frames are used for all subsequent dose-response experiments. After the appropriate time frame of compound/radioligand exposure, the animals are sacrificed and the relevant brain regions dissected (frontal cortex for 5-HT2A and striatum for D2 receptors) and examined for their content of radioactivity. The level of non-specific binding is determined by examining a brain region known not to contain the receptor of interest (in this case the cerebellum) or by administering an excess of compound known pharmacologically to interact with the receptor.

Dosage and Formulation
The serotonin agonist and serotonin antagonist compounds of this invention can be administered as treatment for the control or prevention of central nervous system disorders including obesity, anxiety, depression, psychosis, schizophrenia, sleep and sexual disorders, migraine and other conditions associated with cephalic pain, social phobias, and gastrointestinal disorders such as dysfunction of the gastrointestinal tract motility by any means that produces contact of the active agent with the agent's site of action, i.e., 5-HT2 receptors, in the body of a mammal. It can be administered by any conventional means available for use in conjunction with pharmaceuticals, either as an individual therapeutic agent or in a combination of therapeutic agents. It can be administered alone, but preferably is administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice.
The compounds of the present invention can be administered in such oral dosage forms as tablets, capsules (each of which includes sustained release or timed release formulations), pills, powders, granules, elixirs, tinctures, suspensions, syrups, and emulsions. Likewise, they may also be administered in intravenous (bolus or infusion), intraperitoneal, subcutaneous, or intramuscular form, all using dosage forms well known to those of ordinary skill in the pharmaceutical arts.
The dosage administered will, of course, vary depending upon known factors, such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration; the age, health and weight of the recipient; the nature and extent of the symptoms; the kind of concurrent treatment; the frequency of treatment; and the effect desired. By way of general guidance, a daily dosage of active ingredient can be expected to be about 0.001 to about 1000 milligrams per kilogram of body weight, with the preferred dose being about 0.01 to about 100 mg/kg; with the more preferred dose being about 0.1 to about 30 mg/kg. Advantageously, compounds of the present invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three, or four times daily.
Dosage forms of compositions suitable for administration contain from about 1 mg to about 100 mg of active ingredient per unit. In these pharmaceutical compositions the active ingredient will ordinarily be present in an amount of about 0.5-95% by weight based on the total weight of the composition. The active ingredient can be administered orally in solid dosage forms, such as capsules, tablets and powders, or in liquid dosage forms, such as elixirs, syrups and suspensions. It can also be administered parenterally, in sterile liquid dosage forms.
Gelatin capsules contain the active ingredient and powdered carriers, such as lactose, starch, cellulose derivatives, magnesium stearate, stearic acid, and the like. Similar diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Compressed tablets can be sugar coated or film coated to mask any unpleasant taste and protect the tablet from the atmosphere, or enteric coated for selective disintegration in the gastrointestinal tract. Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance.
In general, water, a suitable oil, saline, aqueous dextrose (glucose), and related sugar solutions and glycols such as propylene glycol or polyethylene glycols are suitable carriers for parenteral solutions. Solutions for parenteral administration preferably contain a water soluble salt of the active ingredient, suitable stabilizing agents, and if necessary, buffer substances. Antioxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid, either alone or combined, are suitable stabilizing agents. Also used are citric acid and its salts, and sodium EDTA. In addition, parenteral solutions can contain preservatives, such as benzalkonium chloride, methyl- or propyl-paraben and chlorobutanol. Suitable pharmaceutical carriers are described in Remington's Pharmaceutical Sciences, supra, a standard reference text in this field.
Useful pharmaceutical dosage-forms for administration of the compounds of this invention can be illustrated as follows:
Capsules
A large number of unit capsules can be prepared by filling standard two-piece hard gelatin capsules each with 100 mg of powdered active ingredient, 150 mg of lactose, 50 mg of cellulose, and 6 mg magnesium stearic.
Soft Gelatin Capsules
A mixture of active ingredient in a digestible oil such as soybean oil, cottonseed oil or olive oil can be prepared and injected by means of a positive displacement pump into gelatin to form soft gelatin capsules containing 100 mg of the active ingredient. The capsules should then be washed and dried.
Tablets
A large number of tablets can be prepared by conventional procedures so that the dosage unit is 100 mg of active ingredient, 0.2 mg of colloidal silicon dioxide, 5 milligrams of magnesium stearate, 275 mg of microcrystalline cellulose, 11 mg of starch and 98.8 mg of lactose. Appropriate coatings may be applied to increase palatability or delay absorption.
Suspension
An aqueous suspension can be prepared for oral administration so that each 5 mL contain 25 mg of finely divided active ingredient, 200 mg of sodium carboxymethyl cellulose, 5 mg of sodium benzoate, 1.0 g of sorbitol solution, U.S.P., and 0.025 mg of vanillin.
Injectable
A parenteral composition suitable for administration by injection can be prepared by stirring 1.5% by weight of active ingredient in 10% by volume propylene glycol and water. The solution is sterilized by commonly used techniques.
