Procedure:
To a solution of 3-{1-perhydro-2H-pyran-2-yl-5-[1-(triphenylmethyl)(1,2,4-triazol-3-yl)]-1H-indazol-3-yl}phenylamine (0.150 g, 0.248 mmol) in 2.5 mL of tetrahydrofuran was added cyclopentanecarbonyl chloride (0.060 mL, 0.496 mmol), followed by triethyl amine (0.173 mL, 1.24 mmol). Completion of the reaction necessitated the addition of 2 more equivalents of reagents and a total reaction time of 48 hours at room temperature. The reaction mixture was then partitioned between ethyl acetate and water. The crude material that was obtained from evaporation of the extracts was not purified further.

Procedure:
In 30 ml of acetonitrile (R)-3-(2-methanesulfonyloxyethyl)-3-(3,4-dichlorophenyl)-1-[(2-chloro-6-fluorophenyl)acetyl]pyrrolidine (3.17 g), prepared as described, supra, is mixed with an equimolar amount of 4-(piperidin-1-yl)piperidine. The reaction mixture is then heated to reflux and refluxed for about ten hours. The mixture is then concentrated under vacuum and the residue is taken up in methylene chloride and washed with a 3N solution of hydrochloric acid, followed by a wash with brine. The organic fraction is dried over magnesium sulfate, filtered, and concentrated in vacuo. The residue precipitates from an acetone/diethyl ether mixture to give the desired title product.

Procedure:
To a solution of sodium hydride (0.35 g) in N,N-dimethylformamide (30 ml) was added dropwise thioacetic S-acid (0.74 ml) with stirring under ice-cooling. The mixture was stirred at the same temperature for 30 minutes. A solution of (2S,4R)-4-methanesulfonyloxy-2-(3-methyl-2-oxoimidazolidin-1-yl)methyl-1-(4-nitrobenzyloxycarbonyl)pyrrolidine (3.17 g) in N,N-dimethylformamide (7 ml) was added to the mixture obtained above with stirring at the same temperature. The mixture was stirred at 80°-90° C. for 2 hours. The reaction mixture was poured into ice-water (100 ml) and extracted twice with ethyl acetate (100 ml). The extract was washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate and evaporated in vacuo. The resulting residue was chromatographed on silica gel (100 g) eluting with a mixture of chloroform and methanol (19:1, V/V). The fractions containing the desired compound were collected and evaporated in vacuo to give (2S,4S)-4-acetylthio-2-(3-methyl-2-oxoimidazolidin-1-yl)methyl-1(4 -nitrobenzyloxycarbonyl)pyrrolidine (1.74 g).

Procedure:
5-Benzyl-3-n-butyl hydantoin (7.38 g, 0.03 mole) was dissolved in dimethylformamide (50 ml.) and added dropwise with stirring to a suspension of sodium hydride (1.44 g. 50% oil dispersion) in dimethylformamide (20 ml). When gassing ceased, iodomethane (2 ml) was added and the mixture warmed to 50° C. and maintained at 50° C. for 5 hours. The mixture was poured into ice/water (500 ml) and extracted with ether. The ether extract was evaporated in vacuo to give a colourless oil which failed to crystallise and was distilled in a Kugelrohr apparatus to give the title compound (6.6 g; 85%) b.p. 145° C./0.02 mm.
