実験手順

To a solution of 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 and triethylamine (0.033 mL, 0.24 mmol) in tetrahydrofuran (3 mL) was added acetyl chloride (0.08 mL, 0.11 mmol). The reaction mixture was stirred at room temperature for 30 min, then water was added. The mixture was partitioned between ethyl acetate and water. Organic layer was separated, washed with water, brine, dried over MgSO4, and concentrated. The residue was purified by chromatography (2% MeOH in EtOAc) to give rac-(2R,3S,4R,5S)-5-(4-acetylamino-2,2-dimethyl-butyl)-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 as a off white gum (60 mg, 94%)
