In a manner similar to the method described in Example 1b, 4-chloro-2-fluorophenylacetonitrile (5 g, 30 mmol) was reacted with 3-chloro-2-fluorobenzaldehyde (5 g, 32 mmol), methanolic solution (25 wt %) of sodium methoxide (21 mL, 92 mmol) in methanol (200 mL) at 45° C. for 5 h to give (Z)-3-(3-chloro-2-fluoro-phenyl)-2-(4-chloro-2-fluoro-phenyl)-acrylonitrile as a white powder (9 g, 97%).
