실험 절차

A solution of chiral methyl 3-(4-((2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamido)phenyl)propanoate (58.8 mg, 0.0936 mmol) in THF (5 ml) was treated with LITHIUM HYDROXIDE MONOHYDRATE (15.7 mg, 0.374 mmol) in water (2.5 ml) and stirred at rt overnight. The mixture was then treated with 1 N HCl to pH 3-4, extracted with ethyl acetate. The organic extracts were washed with water and brine, dried over sodium sulfate and concentrated to give chiral 3-(4-((2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamido)phenyl)propanoic acid (57.7 mg, 100%) as a white solid. MS (ES+) m/z Calcd: [(M+H)+]: 614.17. found: 614.2.
