실험 절차

To a solution of 2-bromo-5-methoxytoluene (50 g, 0.25 mol) in dichloroethane (375 ml), N-bromosuccinimide (48.8 g, 0.275 mol) and AIBN (1.36 g) were added and the reaction was refluxed for 4 h. The cooled solution was filtered and the solvent was evaporated to give a weight of 44.8 g crude 1-Bromo-2-bromomethyl-4-methoxy-benzene (64% yield).
