Procedure

In a manner similar to the method described in Example 380, rac-4-({[(2R,3S,4R,5S)-4-(4-chloro-2-fluoro-phenyl)-3-(3-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carbonyl]-amino}-methyl)-2-methoxy-benzoic acid methyl ester (75.2 mg, 0.117 mmol), was combined with THF (7 ml) and lithium hydroxide hydrate (33.5 mg, 0.798 mmol) in water (3.5 mL). It was stirred at room temperature to give rac-4-({[(2R,3S,4R,5S)-4-(4-Chloro-2-fluoro-phenyl)-3-(3-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carbonyl]-amino}-methyl)-2-methoxy-benzoic acid as a white lyophilized solid (66.6 mg, 89%).
