実験手順

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 (60 mg, 0.096 mmol) prepared in Example 121a was reacted with triethylamine and methanesulfonyl chloride (13 mg, 0.11 mmol) in dichloromethane, followed by the reaction with aqueous HCl solution in tetrahydrofuran to give rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(4-methanesulfonylamino-2,2-dimethyl-butyl)-pyrrolidine-2-carboxylic acid ((S)-3,4-dihydroxy-butyl)-amide as a off white solid (57 mg, 90%)
