(4-Chloro-2-fluoro-phenyl)-acetonitrile → (Z)-3-(3-bromo-2-fluoro-phenyl)-2-(4-chloro-2-fluoro-phenyl)-acrylonitrile

Participants

Reaction Steps

In a manner similar to the method described in Example 1b, 4-chloro-2-fluorophenylacetonitrile (1.39 g, 8.2 mmol) was reacted with 3-bromo-2-fluorobenzaldehyde (Apollo) (2 g, 9.9 mmol), methanolic solution (25 wt %) of sodium methoxide (2 g, 9 mmol) in methanol (40 mL) at 50° C. for 3 h to give (Z)-3-(3-bromo-2-fluoro-phenyl)-2-(4-chloro-2-fluoro-phenyl)-acrylonitrile as a white powder (2.3 g, 79%).
