Procedure

To a solution of (S)-4-{5-[(3,5-Bis-trifluoromethyl-benzyl)-(2-methyl-2H-tetrazol-5-yl)-amino]-7-methyl-8-trifluoromethyl-2,3,4,5-tetrahydro-benzo[b]azepin-1-yl}-cyclohexanecarboxylic acid ethyl ester (0.14 mmol) in methanol (5 mL), add 5N sodium hydroxide (14 mmol). After heating the mixture at 60° C. for 2 h, cool to room temperature and dilute with water (20 mL). Neutralize the mixture using 5M HCl and extract the organics using ethyl actate (3×5 mL). Dry the combined organics over sodium sulfate, filter, and remove the solvent under vacuum. Chromatograph the crude product over silica gel, eluting with methanol/dichloromethane (0-5%) to obtain the separated cis and trans isomers. MS (ES+): 679 (M+H).
