Participants

Reaction Steps

To a stirred solution of (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-carboxylic acid piperidin-4-ylamide trifluoroacetic acid (80 mg, 0.10 mmol) in methylene chloride (10 mL), methanesulfonyl chloride (14 uL, 0.18 mmol) and triethylamine (84 uL, 0.61 mmol) were added and the mixture was stirred at rt for 1 hr. The reaction was quenched with water and the organic layer was separated and dried with sodium sulfate. Removal of solvent gave the crude which was chromatographed on an ISCO machine (0-10% EtOAc/CH2Cl2) to give a white solid. 53 mg.
