Procedure

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 (42.3 mg, 0.10 mmol) and 1-chloro-4-isocyanato-benzene (Aldrich, 45.0 mg, 0.30 mmol) in CH2Cl2 (2 mL) was stirred at rt for 1 h. The reaction mixture was then concentrated and 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 (4-chloro-phenyl)-amide (35.9 mg, 59.3%) as a white amorphous. HRMS (ES+) m/z Calcd for C29H26Cl2F2N3O+H [(M+H)+]: 576.1183, found: 576.1183.
