Procedure

In a manner similar to the method described in Example 1b, 4-chloro-2-fluorophenylacetonitrile (1.9 g, 11 mmol) was reacted with 3-bromobenzaldehyde (Aldrich) (1.57 mL, 13.4 mmol), methanolic solution (25 wt %) of sodium methoxide (2.8 mL, 12 mmol) in methanol (50 mL) at 50° C. for 3 h to give (Z)-3-(3-bromo-phenyl)-2-(4-chloro-2-fluoro-phenyl)-acrylonitrile as a white powder (2.3 g, 60%).
