Reaction Steps

To a solution of ethyl 1-(4-((2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamido)phenyl)piperidine-4-carboxylate (75 mg, 0.108 mmol) in THF (4 mL) was added a solution of LITHIUM HYDROXIDE monohydrate (19.2 mg, 0.458 mmol) in Water (2 mL) dropwise. The reaction mixture was stirred at rt for 2 hrs before it was neutralized with 1N HCl. it was then diluted with EtOAc, washed with water (2×10 mL), brine (2×10 mL), dried and evaporated to give 1-(4-{[(2R,3S,4R,5S)-4-(4-Chloro-2-fluoro-phenyl)-3-(3-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carbonyl]-amino}-phenyl)-piperidine-4-carboxylic acid as a white solid (76 mg, 100%). MS (ES+) m/z Calcd: [(M+H)+]: 669. found: 669.
