Procedure
To a stirred solution of rac {1-[(2R,3S,4R,5S)-3-(3-Chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carbonyl]-piperidin-4-yl}-acetic acid methyl ester (556 mg, 0.92 mmol) in methanol (8 mL), LiOH.H2O (Aldrich, 80 mg) in 1 mL of water was added. The mixture was stirred at 60° C. overnight. The reaction was quenched with addition of water. The mixture was filtered and the filtrate was concentrated to removed methanol. The aqueous layer was washed with EtOAc (2×5 mL) and acidified with 3N HCl. The mixture was then extracted with EtOAc (3×6 mL). The extracts were combined and dried over sodium sulfate and concentrated to give a white solid. 649 mg.
