2.0 g of methyl 2-(4-methylphenyl)benzoate, 1.6 g of N-bromosuccinimide and 0.05 g of α,α'-azobis(isobutyronitrile) were heated in 110 ml of carbon tetrachloride under reflux for 2 hr. The succinimide was filtered off. The filtrate was concentrated, and the residue was recrystallized from a mixed solvent of n-hexane-isopropyl ether to prepare 1.6 g of the title compound.
