A solution of methyl 2-(4-fluorophenyl)-4-methylbenzoate (54.18 g; 0.22 mol), N-bromosuccinimide (39.6 g; 0.22 mol), 2,2′-azobis(2′-methylproprionitrile) (0.25 g; 1.5 mmol) and benzoylperoxide (0.25 g; 1 mmol) in tetrachloromethane (550 ml) was heated at reflux for 6 hours. The solid was filtered and the filtrate evaporated to give methyl 4-bromomethyl-2-(4-fluorophenyl)benzoate as an oil (79.7 g; 79%) which was used in the next step without purification.
