Procedure

A solution of chiral methyl 4-(4-((2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamido)phenyl)butanoate (70.5 mg, 0.110 mmol) in THF (5 ml) was treated with LITHIUM HYDROXIDE MONOHYDRATE (18.5 mg, 0.441 mmol) in water (2.5 ml) and stirred at rt for 16 hrs. The reaction was treated with 1 N HCl (pH 5) and extracted with ethyl acetate, washed with water then sat'd sodium chloride, dried with sodium sulfate, filtered and lyophilized to give chiral-4-(4-((2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamido)phenyl)butanoic acid (67 mg, 97.2%) as a white lyophilized solid. MS (ES+) m/z Calcd: [(M+H)+]: 628.19. found: 628.1.
