Description:
TECHNICAL FIELD 
     The present invention relates to novel organic compounds and compositions which are alpha-1 (α-1) adrenoreceptor antagonism, processes for making such compounds, synthetic intermediates employed in these processes, and a method for inhibiting alpha-1 adrenoceptors and treating benign prostatic hyperplasia (BPH), also called benign prostatic hypertrophy. 
     BACKGROUND OF THE INVENTION 
     Adrenergic neurons play a major role in the innervation of heart, blood vessel and smooth muscle tissue. Compounds capable of interacting with adrenoceptor sites within adrenergic nerve can initiate a variety of physiological responses, including vasoconstriction, vasodilation, and increased or decreased heart rate (chronotropic), contractility (inotropic) and metabolic activity. In the past, various adrenergic compounds have been employed to affect these and other physiological responses. However, many adrenergic compounds do not possess significant selectivity to enable desirable interactions with adrenergic receptor sites. That is, these adrenergic compounds do not demonstrate a high degree of specificity for differing receptor types within adrenergic neurons in order to obtain a desired physiological response separate from other possible, and perhaps less desirable, responses of the system. 
     Benign prostatic hyperplasia (BPH) is a condition which develops in middle-aged and elderly males and refers to the benign overgrowth of the stromal and epithelial elements of the prostate associated with aging. Symptoms of BPH include increased frequency of urination, nocturia, a weak urine stream and hesitancy or delay in starting the urine flow. Chronic consequences of BPH can include hypertrophy of bladder smooth muscle, a decompensated bladder and an increased incidence of urinary tract infection. 
     Typically, BPH begins at an age in the mid-fifties and is the most common cause of urinary tract problems of men of this age. BPH is apparently rare in men prior to age 40, but at age 60, approximately 50% of men have histological evidence of BPH. The prevalence of BPH continues to increase with age until, at age 80, approximately 80% of men have pathological evidence of BPH. 
     Although prostatic hyperplasia is a common finding in older men, the presence of urinary symptoms is the essential feature that distinguishes simple anatomic enlargement of the prostate from prostatism, which is the clinical syndrome whereby the patient experiences significant obstruction of urinary flow. It is not uncommon in older men to have a palpably enlarged prostate without showing the symptoms of prostatism. From the patient&#39;s perspective, however, the incidence and progression of urinary symptoms are more important than the mere presence of an enlarged prostate. 
     The discovery in the 1970&#39;s (M. Caine, et al., Brit. J. Urol., 47: 193-202 (1975)) of large numbers of alpha-adrenergic receptors in the smooth muscle of the prostatic capsule and bladder neck led to the conclusion that there is both a static and a dynamic component to bladder outlet obstruction associated with BPH. The static component derives from the progressive hyperplasia of the prostate with aging, leading to urethral narrowing which causes symptoms of urinary obstruction. Superimposed on this essentially mechanical problem is the variable degree of smooth muscle contraction controlled by the sympatheic nervous system and which is affected by by factors such as stress, cold and sympathomimetic drugs. It is this dynamic component which explains the often rapid fluctuations in symptoms observed in patients with prostatism. 
     The currently most effective treatment for BPH is the surgical procedure of transurethral resection of the prostate (TURP) Since it removes the obstructing tissue (C. Chapple, Br. Med. Journal 304: 1198-1199 (1992)) it is a treatment which is directed to the static and dynamic components of BPH. However, this surgical treatment is associated with rates of mortality (1%) and adverse event (incontinence 2-4%, infection 5-10%, and impotence 5-10%). A non-invasive alternative treatment would thus be highly desirable. 
     The incidental clinical observation that urinary incontinence developed in women during antihypertensive treatment with prazosin (T. Thien, K. P. Delacre, F. M. J. Debruyne, R. A. P. Koene, Br. Med. Journal, 622-623 (1978)) and the experimental work of Caine (op cit.) contributed to the recognition of the potential role of selective α-1 adrenoceptor blockade in diseases of the lower urinary tract. Subsequent studies by several groups have documented the functional role of α-1 adrenoceptors relative to α-2 adrenoceptors in the stromal compartment of the prostate, thereby providing a putative molecular basis for the use of specific α-1 adrenoceptor blockers in the non-surgical management of BPH (C. R. Chapple, M. L. Aubry, S. James, M. Greengrass, G. Bumstock, R. T. Turner-Warwick, Br. J. Urol. 63: 487-496 (1989)). Clinical efficacy of α-1 antagonists in BPH has been demonstrated with several non-selective α-1 blockers, including terazosin (Hytrin™), prazosin, and doxazosin. Treatment periods as short as two to four weeks with α-1 adrenoceptor blockers have shown objective improvements in the mean and maximum urinary flow rates (14-96%) with subjective improvements in patients&#39; symptom scores (R. A. Janknegt, C. R. Chapple, Eur. Urol. 24: 319-326 (1993)). Longer term studies with terazosin, indoramin, prazosin, and doxazosin have similarly demonstrated significant improvements in urinary flow rams and subjective symptom scores (R. A. Janknegt, op. cit., H. Lepor, G. Knapp-Maloney, J. Urol. 145: 263A (1991), W. Chow, D. Hahn, D. Sandhu, Br. J. Urol. 65: 36-38 (1990) and C. R. Chapple, T. J. Christmas, E. J. G. Milroy, Urol. Int. 45: 47-55 (1990)). However, these agents possess similar dose limiting side effects: hypotension, dizziness, and muscle fatigue. There thus exists a need for a &#34;uroselective&#34; α-1 antagonist with reduced side effect liabilities.

     As an indication that the compounds described herein act through binding to α-1 receptors, the compounds have been evaluated for their ability to displace prazosin from its receptor. 
     IN VITRO BINDING ASSAYS 
     In the following, for purposes of discussing alpha-1 receptor subtypes, the IUPAC convention of using lower case letters to define molecular clones and upper case letters to indicate pharmacologically defined receptors has been followed. Moreover, the newly recommended nomenclature for alpha-1 (α 1a , α 1b , α 1d ) has been used. 
     Representative compounds of the invention were evaluated for α-adrenoceptor binding affinity in vitro using [ 3  H]-prazosin as the radioligand and three cloned α-1 adrenoceptors expressed in LTK cells: α-1: α-1a (bovine), α-1b (hamster) and α-1d (rat). Additionally, binding affinity against the pharmacologically defined α-1A adrenoceptor (rat submaxillary gland) was measured. 
     The cDNA clones encoding the α-1 receptors (α-1a, α-1b, and α-1d) were obtained from TULCO (Triangle Universities Licensing Consortium, Research Triangle Park, N.C.) and inserted into the eukaryotic expression vector SnaB30. In this vector, expression of the receptor gene is under the transcriptional control of an SV40 early promoter. Positive drug selection is provided by a neomycin-resistance gene. Mouse fibroblast cells (LTK) were transfected with the α 1  expression plasmids and grown in Dulbecco&#39;s modified Eagle&#39;s medium (DMEM) containing 10% fetal calf serum and 30 μM G418. Stable G418-resistant parental lines were generated, with successful expression of receptor protein monitored using radioligand binding techniques. Stable single cell clones derived from the parental lines were screened in receptor binding assays to identify clones having high receptor density. Roller bottle cultures of the cloned lines were used to provide cell membranes for subsequent receptor binding characterization studies. A cell line containing the SnaB30 vector expressing the human erythropoietin gene served as a negative control. 
     For receptor binding assays, large scale membrane preparations were utilized in which 6 million cells were seeded into small (450 cm 2 ) Corning tissue culture roller bottles. 200 mL of DMEM containing 10% fetal calf serum and 300 μM G418 were added to each roller bottle. A 95% air/5% CO 2  gas mixture (sterile) was injected into each roller bottle prior to sealing. The bottles were then incubated at 37° C. on a roller rack for 5 days. Cells were re-fed with fresh medium after 3 days in culture. 
     On the fifth day of culture, growth medium was removed from cells grown in roller bottles, and the cells were washed twice with PBS (Sigma, 120 mM NaCl, 2.7 mM KCl, 10 mM Na 2  HPO 4  -NaH 2  PO 4 , pH=7.4). Cells were detached from the roller bottles by incubating for 15 minutes at 37° C. in a Tris-EDTA solution (10 mM Tris, 100 mM NaCl, 1 mM EDTA, pH=7.4). The cell suspension from each roller bottle was decanted into tared centrifuge tubes and kept on ice. An aliquot of each cell suspension was generally taken for cell counting. Cells were centrifuged at 3000×G for 5 min at 2°-4° C., washed with PBS and recentrifuged. The supernatant was decanted and the pellet weighed to determine the wet weight of cells. Cells were washed a final time in 40 vol 5 mM Tris-HCl, 5 mM EDTA, pH=7.7, and centrifuged at 40,000×G for  10 minutes. Cells were homogenized in 10 mL of 50 mM Tris-HCl, 5 mM EDTA (pH=7.4) and diluted to 40 mL/tube. Homogenates were centrifuged at 40,000×G for 10 minutes. The supernatant was decanted and the pellets rehomogenized in 50 mM Tris-HCl (pH=7.4) and centrifuged as before. The supernatant was decanted and the homogenate resuspended in 6.25 volumes (per gram wet weight of 50 mM Tris-HCl and aliquots of the pooled homogenates s frozen in liquid N 2  and stored at -70° C. until the time of assay. Rat submaxillary glands were used for α-1A receptors and were prepared essentially as described (Michel, A. D., Loury, D. N. and Whiting, R. L., Brit. J. Pharmacol. 98: 83-889 (1989)). 
     Receptor binding assays for α-1 receptors were performed essentially as described by Greengrass and Bremner (Eur. J. Pharmacol. 55: 323-326 (1979)). Briefly, plastic Bioblocks™ (DBM Scientific, Valencia, Calif.) were incubated at 25° C. for 50 minutes with 500 μL of membrane homogenate (diluted with an additional 96 volumes [for cloned receptors, 12 volumes for submaxillary gland] in 50 mM Tris-HCl buffer (pH=7.7 at the time of assay), 450 μL of [ 3  H]prazosin (0.2 nM final concentration, 75-85 Ci/mmole, DuPont-NEN Corp., Boston, Mass.) and 50 μL of either water (for total binding) or 10 μM phentolamine (final concentration, for non-specific binding). Following equilibration, bound radioligand was separated from free on GF/B filters (presoaked in 0.5% polyethyleneimine) using either a Brandel or Packard cell harvester. Radioactivity was determined by standard liquid scintillation techniques. Data were analyzed as previously described (Hancock, A. A., Kyncl, J. J., Martin, Y. C. and DeBemardis, J. F.,  J. Receptor Res. 8: 23-46 (1988)). 
     Canine prostate strips were used in vitro as previously described (Hieble, J. P., Boyce, A. J. and Caine, M., Fed. Proc., 45: 2609-2614 (1986)), to determine antagonist potencies against phenylephrine-induced contractions. 
     The results are shown in Table I. The results show that the compounds of the invention bind to the α-1 adrenoceptor and show varying degrees of specificity for the α-1a receptor.

     FUNCTIONAL ANTAGONISM AT α1 ADRENOCEPTORS 
     Functional assays indicative of pharmacologically defined α-1 adrenoceptors were used to further characterize compounds. Inhibition of phenylephrine (PE)-induced contraction of canine prostate smooth muscle can be correlated with α-1A adrenoceptor activation. Inhibition of PE-induced contraction of rat spleen is representative of α-1B adrenoceptor antagonism and-inhibition of PE-induced contraction of rat was deferens correlates with α-1A adrenoceptor antagonism (R. P. Burt, C. R. Chapple and I. Marshall, Br. J. Pharmacol. 107: P324 (1992)). For each of these models, agonist dose response curves were repeated against increasing concentrations of test agent to derive a Schild plot [log (EC 50  -1) against log (molarity of test agent)] to determine the pA 2 . Data for prazosin, terazosin and doxazosin actually demonstrate a more potent effect on spleen smooth muscle by approximately an order of magnitude. 
     Canine prostate strips were used in vitro as previously described (Hieble, J. P., Boyce, A. J. and Caine, M., Fed. Proc., 45: 2609-2614 (1986)), to determine antagonist potencies against phenylephrine-induced contractions. 
     The results are shown in Tables 2a and 2b. The results show that the compounds of the invention exhibit functional antagonism of α-1 adrenoceptors.

     IN VIVO DETERMINATION OF INTRAURETHRAL PRESSURE (IUP) IN CANINES 
     The intraurethral pressure (IUP) model in aged canines is an accepted model of measuring the effect of prostate smooth muscle contraction on urethral tone. Canines also have an enclosed prostate covering the urethral shaft thus providing an anatomical correlate with humans. 
     Beagle dogs (Marshall Farms) greater that 2 years of age and weighing between 12 and 15 kg were pre-anesthetized with thiopental sodium 15 mg/kg i.v. (Pentothal™, Abbott) and then placed under general anesthesia (isoflurane). A 7F Swan-Ganz balloon catheter (Multiflex - list no. 41224-01, Abbott) was lubricated with a water soluble jelly, inserted into the urethral orifice and advanced approximately 40 cm in male dogs (considerably less in females) until the balloon tip was placed well inside the bladder. The balloon was then inflated with 1 mL of room air and the catheter slowly withdrawn just past the first resistance that is felt at the bladder neck. Preliminary experiments in which dogs were sacrificed after such placement confirmed that this technique results in consistent positioning of the balloon within the prostatic urethra in males or the corresponding location in females. The balloon port of the catheter was connected to a Gould Statham P23Dd pressure transducer interfaced to a computerized data acquisition system (Modular Instruments, Inc., Malvern, Pa.) for the measurement of intraurethral pressure (IUP). 
     Dogs were then treated with propranolol to block the β-adrenoceptor agonist effects of test agonists. Dose-response curves of the intraurethral pressor effect of epinephrine (EPI) were obtained before and after each of up to 3 increasing doses of a test antagonist (i.v.). Fifteen minutes was allowed after each antagonist dose for equilibration before the next agonist dose-response was initiated. The increase in IUP caused by a given agonist dose was allowed to return to baseline before the next dose was given. The estimated antagonist dissociation constant (in vivo pseudo pA 2 ) was determined by Schild analysis (Brune, et al., Drug Development Research (1995) in press). 
     The results are shown in Table 3. The results indicate that the compounds of the invention inhibit EPI induced increases in IUP.

     SPONTANEOUSLY HYPERTENSIVE RAT (SHR) MODEL 
     The SHR model historically has been used as a predictor for the hypotensive effects of α-1 adrenoceptor antagonism. Male spontaneously hypertensive rots were anesthetized and the left femoral artery and vein catheterized for the measurement of mean arterial pressure (MAP) and drug administration respectively. The arterial catheter was connected to a Gould Statham p23 ID transducer and the pressure waveform was recorded. MAP (mm Hg) and heart rate (HR, beats/min.) were determined on-line using a BUXCO Cardiovascular Analyzer. After a 30 minute pre-dose control period, each rat was given one dose of a test antagonist i.v. and the MAP and HR were monitored for an additional 2.5 hours. The area under the hypotensive response curve up to 60 minutes post dosing (T 60  AUC) was determined using a trapezoidal rule integration of the percent change from control arterial pressure dataset. 
     The results are shown in Table 4. The results show that the compounds of the invention are weakly hypotensive.

     PHARMACEUTICAL COMPOSITIONS 
     The present invention also provides pharmaceutical compositions which comprise compounds of the present invention formulated together with one or more non-toxic pharmaceutically acceptable carriers. The pharmaceutical compositions may be specially formulated for oral administration in solid or liquid form, for parenteral injection, or for rectal administration. 
     The pharmaceutical compositions of this invention can be administered to humans and other animals orally, rectally, parenterally, intracisternally, intraperitoneally, topically (as by powders, ointments, or drops), bucally, or as an oral or nasal spray. The term &#34;parenteral&#34; administration as used herein refers to modes of administration which include intravenous, intramuscular, intraperitoneal, intrasternal, subcutaneous and intraarticular injection and infusion. 
     Pharmaceutical compositions of this invention for parenteral injection comprise pharmaceutically acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions as well as sterile powders for reconstitution into sterile injectable solutions or dispersions just prior to use. Examples of suitable aqueous and nonaqueous careers, diluents, solvents or vehicles include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), and suitable mixtures thereof, vegetable oils (such as olive oil), and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of coating materials such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. 
     These compositions may also contain adjuvants such as preservative, wetting agents, emulsifying agents, and dispersing agents. Prevention of the action of microorganisms may be ensured by the inclusion of various and bacterial and antifungal agents, for example, paraben, chlorobutanol, phenol sorbic acid, and the like. It may also be desirable to include isotonic agents such as sugars, sodium chloride, and the like, Prolonged absorption of the injectable pharmaceutical form may be brought about by the inclusion of agents which delay absorption such as aluminum monostearate and gelatin. 
     In some cases, in order to prolong the effect of the drug, it is desirable to slow the absorption of the drug from subcutaneous or intramuscular rejection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle. 
     Injectable depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(othoesters) and poly(anhydrides) Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues. 
     The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium just prior to use. 
     Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case, of capsules, tablets and pills, the dosage form may also comprise buffering agents. 
     Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. 
     The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions which can be used include polymeric substances and waxes. 
     The active compounds can also be in micro-encapsulated form, if appropriate, with one or more of the above-mentioned excipients. 
     Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethyl formamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. 
     Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents. 
     Suspensions, in addition to the active compounds, may contain suspending agents as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar, and tragacanth, and mixtures thereof. 
     Compositions for rectal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at room temperature but liquid at body temperature and therefore melt in the rectum and release the active compound, 
     Compounds of the present invention can also be administered in the form of liposomes. As is known in the art, liposomes are generally derived from phospholipids or other lipid substances. Liposomes are formed by mono- or multi-lamellar hydrated liquid crystals that are dispersed in an aqueous medium. Any non-toxic, physiologically acceptable and metabolizable lipid capable of forming liposomes can be used. The present compositions in liposome form can contain, in addition to a compound of the present invention, stabilizers, preservatives, excipients, and the like. The preferred lipids are the phospholipids and the phosphatidyl cholines (lecithins), both natural and synthetic. 
     Methods to form liposomes are known in the art. See, for example, Prescott, Ed., Methods in Cell Biology, Volume XIV, Academic Press, New York, N.Y. (1976), p. 33 et seq. 
     Dosage forms for topical administration of a compound of this invention include powders, sprays, ointments and inhalants. The active compound is mixed under sterile conditions with a pharmaceutically acceptable career and any needed preservatives, buffers, or propellants which may be required. Opthalmic formulations, eye ointments, powders and solutions are also contemplated as being within the scope of this invention. 
     Actual dosage levels of active ingredients in the pharmaceutical compositions of this invention may be varied so as to obtain an amount of the active compound(s) that is effective to achieve the desired therapeutic response for a particular patient, compositions, and mode of administration. The selected dosage level will depend upon the activity of the particular compound, the route of administration, the severity of the condition being treated, and the condition and prior medical history of the patient being treated. However, it is within the skill of the art to start doses of the compound at levels lower than-required for to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved. 
     Generally dosage levels of about 0.01 to about 50, more preferably of about 0.05 to about 5 mg of active compound per kilogram of body weight per day are administered orally to a mammalian patient. If desired, the effective daily dose may be divided into multiple doses for purposes of administration, e.g. two to four separate doses per day. 
     While the compounds of the invention can be administered as the sole active pharmaceutical agent, they can also be used in combination with a 5-α reductase inhibitor. A particularly preferred 5-α reductase inhibitor for use in coadministration with compounds of the present invention is the compound having the generic name finasteride. 
     Methods for preparing the compounds of the invention are shown in Schemes I-VI. In the following Schemes, R 1  and R 2  are independently hydrogen, alkoxy, hydroxy, alkyl, halo, carboxy, or alkoxycarbonyl. 
     Scheme I illustrates the general procedure for the preparation of the compounds of the invention. Compound 1, prepared by the procedures described in U.S. Pat. No. 4,618,683, which is incorporated herein by reference, is reacted with chloroacetonitrile under mildly basic conditions (for example. diisopropylethylamine, triethylamine and the like) to afford the cyanomethyl compound 2. The nitrile is dissolved in an inert solvent (for example, THF, ether and the like) and treated with a reducing agent (for example, lithium aluminum hydride, diborane or catalytic hydrogenation and the like) to give the ethylene diamine compound 3. The diamine is reacted with the isocyanate 4 of the aromatic compound U, prepared from the aromatic amine by treatment with phosgene or triphosgene, to give the pyrimidine dione 5. 
     Alternatively as shown in Scheme II, the diamine can by prepared by taking diester 6, prepared by the procedures described in U.S. Pat. No. 5,049,564, which is incorporated herein by reference, in an inert solvent (for example, THF or ether and the like) and reducing the diester with a reducing agent (for example, lithium aluminum hydride or diborane and the like) to give the diol 7. The diol is reacted with an appropriate reagent to form leaving groups (for example, a mesylate or rosylate and the like) giving compound 8. Treatment of compound 8 with the appropriate diamine (H 2  N--(CH 2 ) n  --NH 2  or synthon) with heating gives the pyrrolidine amine 9. Compound 9 can be further elaborated by the procedures described in Scheme I to give the final compound 10. 
     The compounds of the invention can also be prepared by the procedures illustrated in Scheme III. Compound 4a is reacted with a haloalkyl isocyanate (for example, 2-chloroethyl isocyanate) by the procedures described in Eur. J. Med. Chem. 28: 499 (1993), which is incorporated herein by reference, to give haloalkyl urea 11. Compound 1, as previously described in Scheme I, is reacted with compound 11 to give the final product 5. 
     The preparation of chiral cis intermediates is shown in Scheme IV. Dihydronaphthylene-1-carboxylic acid 12, is esterified (for example, using diazomethane or alcohol with a trace of sulfuric acid) to give compound 13. Treatment of the α,β-unsaturated ester with lithium cyanide in DMF and acetic acid affords the cyano compound 14. The nitrile ester is hydrolyzed (for example, using KOH in ethanol/water) to give the dicarboxylic acid 15. Treatment of the diacid with acetic anhydride under reflux affords the cyclic art hydrides 16a and 16b. The anhydrides are reacted with optically active (S)-(-)-α-methylbenzylamine to give both the (3aR,9bR)-compound 18 and the (3aS,9bS)-compound 17 as a mixture of imides separable by crystallization. Compounds 17 and 18 are reduced (for example, with diborane) to give the corresponding N-substituted pyrrolidine compounds 19 and 20. Catalytic hydrogenation affords chiral intermediates 21 and 22. These pyrrolidines can be further elaborated by the procedures described in Schemes I and III to give the final products. 
     A preferred embodiment is shown in Scheme V. Compound 23 wherein R is a carboxy protecting group is reacted with 2-chloroethyl isocyanate to give urea 24. Compound 24 is reacted with compound 25. in a solvent such as DMSO in the presence of a non-nucleophilic base such as diisopropylethylamine to give the ring closed coupled product 27. 
     Another preferred embodiment in shown in Scheme VI. The aromatic carboxy-protected amine 28 is reacted with triphosgene to give isocyanate 29. The isocyanate is reacted with amine 30, prepared by the procedure described in Scheme I or II, to cyclize and couple in one step to give compound 31. ##STR19##
