実験手順
Step C In a manner similar to the method described in Example 1b, 4-chloro-2-methylbenzyl cyanide (1.2 g, 7.2 mmol) was reacted with 3-chloro-2-fluorobenzaldehyde (1.38 g, 8.7 mmol), methanolic solution (25 wt %) of sodium methoxide (1.82 mL, 8 mmol) in methanol (50 mL) at 50° C. for 3 h to give (Z)-3-(3-chloro-2-fluoro-phenyl)-2-(4-chloro-3-methyl-phenyl)-acrylonitrile as a white solid (2.0 g, 91%).
