Procedure
To 110 ml of carbon tetrachloride, were added 10.5 g of 4'-methyl-2-cyanobiphenyl, 9.79 g of N-bromosuccinimide and 120 mg of 2,2'-azodiisobutylonitrile, followed by heating under reflux for 2 hours. After hot filtration of the insoluble matter, the filtrate was allowed to cool to room temperature. Crystals so precipitated were collected by filtration, whereby 6.6 g of the title compound was obtained.
