In a manner similar to the method described in Example 1b, 4-chloro-2-fluorophenylacetonitrile (4.5 g, 26 mmol) was reacted with 2,3-difluorobenzaldehyde (Aldrich) (4.5 g, 32 mmol), methanolic solution (25 wt %) of sodium methoxide (6.3 g, 29 mmol) in methanol (135 mL) at 50° C. for 3 h to give (Z)-2-(4-chloro-2-fluoro-phenyl)-3-(2,3-difluoro-phenyl)-acrylonitrile as a white powder (6.85 g, 88%).
