Procedure

In a manner similar to the method described in Example 1c, [3,3-dimethyl-but-(E)-ylideneamino]-acetic acid tert-butyl ester prepared in Example 1a (1.1 g, 5 mmol) was reacted with (Z)-2-(4-bromo-phenyl)-3-(3-chloro-2-fluoro-phenyl)-acrylonitrile (1.2 g, 3.6 mmol) prepared in Example 54a, AgF (1.3 g, 10 mmol), and triethylamine (2 g, 20 mmol) in dichloromethane (100 mL) at room temperature for 3 h to give rac-(2R,3S,4R,5S)-4-(4-bromo-phenyl)-3-(3-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid tert-butyl ester as a white foam (1.1 g, 56%).
