실험 절차

In a manner similar to the method described in Example 1c, [2,2-dimethyl-prop-(E)-ylideneamino]-acetic acid tert-butyl ester prepared in Example 51a (1 g, 5 mmol) was reacted with (Z)-3-(3-chloro-2-fluoro-phenyl)-2-(4-chloro-phenyl)-acrylonitrile (0.8 g, 2.7 mmol) prepared in Example 26a, AgF (1.5 g, 12 mmol), and triethylamine (2 g, 20 mmol) in dichloromethane (50 mL) at room temperature for 24 h to give (2R,3S,4R,5S)-5-tert-Butyl-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-phenyl)-4-cyano-pyrrolidine-2-carboxylic acid tert-butyl ester as a white foam (0.4 g, 30%).
