Reaction Steps

476 mg of dibenzoyl peroxide were added to a solution of 5.87 g of 2-methylbenzothiazole and 15.4 g of N-bromosuccinimide in 60 ml of carbon tetrachloride at room temperature and the resulting mixture was stirred under reflux for 9 hours. At the end of this time, the reaction mixture was filtered and the resulting filtrate was concentrated by evaporation under reduced pressure to give a crude crystalline solid which was purified by column chromatography through silica gel using a 10:1 by volume mixture of hexane and ethyl acetate to give 6.10 g (yield 68%) of the title compound as a solid having a metling point of 43° to 45° C.
