Procedure

In a manner similar to the method described in Example 4, 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) was reacted with 4-carboxymethyl-2-ethoxy-benzoic acid ethyl ester (Aldrich, 50.4 mg, 0.20 mmol), in the presence of HATU (91.0 mg, 0.24 mmol) and iPr2NEt (0.1 mL) in CH2Cl2 (2 mL) at rt for 2 hrs to give rac-4-{2-[(2S,3S,4S)-2-(3-chloro-2-fluoro-phenyl)-3-(4-chloro-2-fluoro-phenyl)-3-cyano-4-(2,2-dimethyl-propyl)-pyrrolidin-1-yl]-2-oxo-ethyl}-2-ethoxy-benzoic acid ethyl ester (52.6 mg, 37.6%) which was used in the next step without further purification.
