Procedure
In a manner similar to the method described in Examples 1e, rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid trifluoroacetic acid prepared in Example 26c (0.38 g, 0.55 mmol) was reacted with methyl 4-aminobenzoate (0.33 g, 2.2 mmol), HATU (0.38 g, 1 mmol) and iPr2NEt (0.29 mL, 1.7 mmol) in CH2Cl2 at room temperature to give rac-4-{[(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carbonyl]-amino}-benzoic acid methyl ester as a white solid (0.11 g, 34%).
