Procedure

A mixture of 2-(4-{[(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]-amino}-phenyl)-butyric acid methyl ester (23 mg, 0.036 mmol) was dissolved in THF (0.9 mL) and methanol (0.3 mL), then 2N LiOH (1 mL) was added and stirred at room temperature for 2 hours. The mixture was diluted with water and ethyl acetate. The organic phase was separated then concentrated to yield 2-(4-{[(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]-amino}-phenyl)-butyric acid (16.4 mg, 72.9%) as an off-white powder. HRMS (ES+) m/z Calcd for C33H33Cl2F2N3O3+H [(M+H)+]: 628.1940. found: 628.1939.
