A mixture of 5.0 g of 3,4-dichlorophenyl 4'-methyl-4-biphenylyl ketone, 2.7 g of N-bromosuccinimide and 20 mg of azaisobutyronitrile in 70 ml of carbon tetrachloride is heated to boiling under reflux. The precipitated material is filtered and the filtrate is evaporated. The residue is recrystallized from toluene/cyclohexane. 3,4-Dichlorophenyl 4'-bromomethyl-4-biphenylyl ketone is obtained.
