A brown solution of 70 g of 2,6-bis(methylthio)-N-(1,1-dimethylethyl)benzenesulfonamide in 200 ml trifluoroacetic acid was stirred at room temperature. After 10 minutes, a heavy precipitate formed, the suspension was stirred for 18 hours. The resulting solid was collected by filtration and dissolved in 10% NaOH, filtered and the filtrate acidified with 10% HCl. The precipitated solid was washed with water and air dried to provide 48 g of 2,6-bis(methylthio)benzenesulfonamide, m.p. 197°-199°.
