Reaktionsschritte
2.0 g (8.8 mmol) of methyl 2-(4'-methylphenyl)benzoate, 1.6 g (9.0 mmol) of N-bromosuccinimide and 0.05 g of α,α'-azobis(isobutyronitrile) [another name; 2,2'-azobis(isobutyronitrile)] were dissolved in carbon tetrachloride (110 ml), followed by heating under reflux for 2 hours. The resultant mixture was filtered to remove insolubles, and then vacuum concentration was effected. The residue was recrystallized from a n-hexane/isopropyl ether mixed solvent to give 1.6 g of the title compound (yield; 59%).
