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 (84.6 mg, 0.20 mmol) and 4-isocyanato-benzoic acid methyl ester (Aldrich, 53.1 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 4-{[(2S,3S,4S)-2-(3-chloro-2-fluoro-phenyl)-3-(4-chloro-2-fluoro-phenyl)-3-cyano-4-(2,2-dimethyl-propyl)-pyrrolidine-1-carbonyl]-amino}-benzoic acid methyl ester (89.7 mg, 74.7%) which was used in the next step without further purification.
