Procedure

To a mixture of 4-({[(2S,3S,4S)-2-(3-chloro-2-fluoro-phenyl)-3-(4-chloro-2-fluoro-phenyl)-3-cyano-4-(2,2-dimethyl-propyl)-pyrrolidine-1-carbonyl]-amino}-methyl)-benzoic acid methyl ester (108.0 mg, 0.18 mmol) in THF/MeOH (0.6 mL/0.2 mL) was added 4 N LiOH (0.2 mL), and the reaction mixture was stirred at rt for 2 hrs. The reaction mixture was concentrated and quenched with 2 NH2SO4, extracted with EtOAc, and washed with water, brine. The organic phase was separated, and dried over Na2SO4. The mixture was then concentrated to 4-({[(2S,3S,4S)-2-(3-chloro-2-fluoro-phenyl)-3-(4-chloro-2-fluoro-phenyl)-3-cyano-4-(2,2-dimethyl-propyl)-pyrrolidine-1-carbonyl]-amino}-methyl)-benzoic acid (101.2 mg, 95.9%). FIRMS (ES+) m/z Calcd for C31H29Cl2F2N3O3+H [(M+H): 600.1627; Found: 600.1629.
