Procedure

In a manner similar to the method described in Examples 122a and 122b, rac-(2R,3S,4R,5S)-5-(4-amino-2,2-dimethyl-butyl)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-pyrrolidine-2-carboxylic acid [2-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl)-ethyl]-amide (80 mg, 0.13 mmol) prepared in Example 121a was reacted with triethylamine and benzoyl chloride (22 mg, 0.16 mmol) in tetrahydrofuran, followed by the reaction with aqueous HCl solution in tetrahydrofuran to give rac-(2R,3S,4R,5S)-5-(4-benzoylamino-2,2-dimethyl-butyl)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-pyrrolidine-2-carboxylic acid ((S)-3,4-dihydroxy-butyl)-amide as a off white solid (57 mg, 90%)
