Procedure
400.0 g (2.53 mol) of potassium permanganate are added in portions at 80° C. over a period of 2 h to a solution of 106.0 g (0.40 mol) of 2-methyl-5-nitrobenzenesulfonic acid and 80.0 g (0.58 mol) of potassium carbonate in 1300 ml of water. The reaction temperature is maintained at between 80° and 95° C.
