Procedure

0.9 g of 7-acetylbenzo-1,2,3-thiadiazole is dissolved in 20 ml of chloroform, and 0.88 g of bromine is added dropwise at room temperature. Stirring is then continued for 2 hours at the same temperature, during which process a yellow precipitate forms. This precipitate is filtered off, washed with hexane and dried. The title compound which is thus obtained melts at 155°-157° C.
