Procedure

p-Toluenesulfonyl chloride (0.52 mol, 100 g), N-bromosuccinimide (0.62 mol, 110.3 g), and benzoyl peroxide (5 g) were heated to reflux in carbon tetrachloride (500 ml) for 1 hour. The mixture was filtered and the filtrate was concentrated in vacuo. The residue was triturated with isopropyl ether to afford 40.1 g of title product as a white solid; m.p. 70°-73° C.
