To a solution of 4-chloro-2-fluorophenylacetonitrile (Matrix) (5 g, 30 mmol) and 3-chloro-2-fluorobenzaldehyde (Oakwood) (5 g, 32 mmol) in methanol (200 mL) was slowly added a methanolic solution (Aldrich, 25 wt. %) of sodium methoxide (21 mL, 92 mmol). The reaction mixture was heated and stirred at 45° C. for 5 h. The mixture was cooled to room temperature and filtered. The white precipitate was washed with water, cold methanol, and then dried under reduced pressure to afford (Z)-3-(3-chloro-2-fluoro-phenyl)-2-(4-chloro-2-fluoro-phenyl)-acrylonitrile as a white powder (8 g, 86%).
