Imidazole-1-carboxylic acid (1-methanesulfonyl-piperidin-4-yl)-amide → rac-(2S,3S,4S)-2-(3-chloro-2-fluoro-phenyl)-3-(4-chloro-2-fluoro-phenyl)-3-cyano-4-(2,2-dimethyl-propyl)-pyrrolidine-1-carboxylic acid (1-methanesulfonyl-piperidin-4-yl)-amide

Participants

Reaction Steps

A mixture of rac-(2S,3S,4S)-2-(3-chloro-2-fluoro-phenyl)-3-(4-chloro-2-fluoro-phenyl)-4-(2,2-dimethyl-propyl)-pyrrolidine-3-carbonitrile (30.5 mg, 0.072 mmol) and imidazole-1-carboxylic acid (1-methanesulfonyl-piperidin-4-yl)-amide (75.4 mg, 0.277 mmol) in CH2Cl2 (4 mL) was stirred at rt for 72 hrs. The reaction mixture was then purified by flash column to give rac-(2S,3S,4S)-2-(3-chloro-2-fluoro-phenyl)-3-(4-chloro-2-fluoro-phenyl)-3-cyano-4-(2,2-dimethyl-propyl)-pyrrolidine-1-carboxylic acid (1-methanesulfonyl-piperidin-4-yl)-amide (15.7 mg, 34.7%). HRMS (ES+) m/z Calcd for C29H34Cl2F2N4O3S+H [(M+H)+]: 627.1770; Found: 627.1770.
