A solution of bromine (0.81 g) in chloroform (5 ml) was added dropwise to a stirred solution of 4'-acetyl2'-(2,4-difluorophenylthio)methanesulfonanilide (1.8 g) and benzoyl peroxide (8 mg) in chloroform (20 ml). After stirring for 1 hour at room temperature, the mixture was washed with water and an aqueous solution of sodium bisulfite successively. The organic layer was dried and concentrated to give 4'-bromoacetyl-2'(2,4-difluorophenylthio)methanesulfonanilide.
