2,4-Dichlorophenylacetonitrile → (Z)-3-(3-chloro-2-fluoro-phenyl)-2-(2,4-dichloro-phenyl)-acrylonitrile

Participants

Reaction Steps

In a manner similar to the method described in Example 1b, 2,4-dichlorobenzyl cyanide (6 g, 32 mmol) was reacted with 3-chloro-2-fluorobenzaldehyde (6 g, 38 mmol), methanolic solution (25 wt %) of sodium methoxide (30 mL, 131 mmol) in methanol (200 mL) at 50° C. for 3 h to give (Z)-3-(3-chloro-2-fluoro-phenyl)-2-(2,4-dichloro-phenyl)-acrylonitrile as a white powder (7 g, 67%).
