Procedure

4 ml of chlorosulfonic acid are added slowly to 1 g (0.067 mol) of 2,6-dimethylbenzoic acid and the reaction mixture is stirred for 1 hour at 55° C. After cooling, the mixture is poured into 100 ml of iced water. The precipitate formed is filtered off, washed with cold water and then dried in a desiccator under vacuum to give 1.22 g of the expected product in the form of a white solid (yield=73%).
