Procedure

In a manner similar to the method described in Examples 42d, rac-(2R,3S,4R,5S)-5-(4-acetylamino-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 prepared in Example 122a (60 mg, 0.09 mmol) was reacted with aqueous HCl solution (1 N, 1 mL, 1 mol) in tetrahydrofuran (5 mL) at room temperature for 2 h to give rac-(2R,3S,4R,5S)-5-(4-acetylamino-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 white solid (50 mg, 89%).
