実験手順

In a manner similar to the method described in Example 1c, [3-methyl-but-(E)-ylideneamino]-acetic acid tert-butyl ester prepared in Example 1a (2.1 g, 10 mmol) was reacted with (Z)-3-(4-bromo-thiophen-2-yl)-2-(4-chloro-2-fluoro-phenyl)-acrylonitrile (2.7 g, 8 mmol) prepared in Example 70a, AgF (1.5 g, 12 mmol), and triethylamine (2.7 mL, 20 mmol) in dichloromethane (120 mL) at room temperature for 18 h to give rac-(2R,3R,4R,5S)-3-(4-bromo-thiophen-2-yl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid tert-butyl ester as a white foam (0.9 g, 20%).
