N-bromobutanimide → 4-(Bromomethyl)-1-chloro-2-methoxybenzene

Participants

Reaction Steps

To a solution of 4-chloro-3-methoxytoluene (5.65 g) and N-bromosuccinimide (6.74 g) in anhydrous dichloromethane (60 mL) was added 2,2′-azolbis(4-methoxy-2,4-diaethylvaleronitrile) (674 mg). After stirring for 3 hours under reflux, the mixture was washed with water and brine, dried over magnesium sulfate and evaporated in vacuo. The residue was triturated with hexane to give 4-chloro-3-methoxybenzyl bromide as white powders (2.00 g).
