Procedure

A solution of 3-(1,1,2,2-tetrafluoroethoxy)toluene (6.70 g, 32.2 mmol), N-bromosuccinimide (5.73 g, 32.2 mmol) and 2,2′-azobis(isobutyronitrile) (10 mg) in carbon tetrachloride (30 ml) was heated under reflux for 0.5 hr. After cooling the reaction solution to room-temperature, the white precipitate was removed by filtration and the precipitate was washed with diethyl ether. The solvent of the collected filtrate was evaporated under reduced pressure to give a crude product of 3-(1,1,2,2-tetrafluoroethoxy)benzyl bromide as a pale-yellow liquid.
