In a manner similar to the method described in Example 1b, 4-chloro-2-fluorophenylacetonitrile (3.4 g, 20 mmol) was reacted with 3-chloro-5-fluoro-benzaldehyde (Aldrich) (3.77 g, 24 mmol), methanolic solution (25 wt %) of sodium methoxide (4.99 mL, 22 mmol) in methanol (90 mL) at 50° C. for 3 h to give (Z)-3-(3-chloro-5-fluoro-phenyl)-2-(4-chloro-2-fluoro-phenyl)-acrylonitrile as a white powder (5.5 g, 90%).
