실험 절차

In a manner similar to the method described in Example 1b, 4-chloro-2-methoxybenzyl cyanide (2 g, 10 mmol) prepared in Example 58a Step B was reacted with 3-chlorobenzaldehyde (2 g, 14 mmol), methanolic solution (25 wt %) of sodium methoxide (15 mL, 66 mmol) in methanol (50 mL) at 50° C. for 5 h to give (Z)-2-(4-chloro-2-methoxy-phenyl)-3-(3-chloro-phenyl)-acrylonitrile as a white powder (1.9 g, 63%).
