Reaction Steps
A solution of 5-trifluoromethyl-m-xylene (3.4 g) and dibenzoyl peroxide (0.25 g) in 100 ml of benzene at reflux is treated with N-bromosuccinimide (4.4 g) in portions. The mixture is heated until a negative potassium iodide test is obtained. The reaction mixture is cooled and concentrated in vacuo. The residue is triturated with n-hexane and the solids are removed by filtration. The filtrate is evaporated to give the oily crude benzyl bromide.
