Reaction Conditions

Reaction Steps

The 467.3 g of 2-cyano-4'-methylbiphenyl prepared above are dissolved in 4.7l of 1,2-dichloroethane in the presence of 467.3 g of N-bromosuccinimide and 9.3 g of benzoyl peroxide. The mixture is heated very gradually so as to have good control over the exothermic effect. It is subsequently refluxed for 4 h, cooled to 50° C. and then washed 3 times with hot water and dried and the organic phase is concentrated to give cream-colored crystals.
