실험 절차

In a manner similar to the method described in Example 100b, [[3-methyl-3-(5-methyl-furan-2-yl)-but-(E)-ylideneamino]-acetic acid tert-butyl ester prepared in Example 125a (1.7 g, 6 mmol) was reacted with (Z)-3-(3-chloro-2-fluoro-phenyl)-2-(4-chloro-2-fluoro-phenyl)-acrylonitrile (1.48 g, 4.8 mmol) prepared in Example 52a, AgF (0.9 g, 7 mmol), and triethylamine (1.7 mL, 12 mmol) in dichloromethane (100 mL) at room temperature for 18 h, followed by the reaction with DBU (5.7 ml) in tert-butanol (10 mL) at 100° C. for 2 h to give rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-[2-methyl-2-(5-methyl-furan-2-yl)-propyl]-pyrrolidine-2-carboxylic acid tert-butyl ester as a yellow solid (1.3 g, 46%).
