Procedure

A mixture of rac-(5-{[(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}-4H-[1,2,4]triazol-3-yl)-acetic acid methyl ester (20 mg, 0.033 mmol) was dissolved in THF (0.6 mL) and methanol (0.2 mL), then 2N LiOH (0.2 mL) was added and stirred at room temperature for 3 hours. The mixture was concentrated and diluted with water and ethyl acetate. The organic phase was separated then concentrated to yield rac-(5-{[(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}-4H-[1,2,4]triazol-3-yl)-acetic acid (6.7 mg, 34%) as an off-white powder. HRMS (ES+) m/z Calcd for C27H26Cl2F2N6O3+H [(M+H)+]: 591.1485. found: 591.1483.
