Procedure

102 ml of 30% hydrogen peroxide solution are added dropwise at a temperature of +10° C. to a solution in 500 ml of concentrated acetic acid of 219 g of 2-benzylthiophenylsulfonamide obtained in accordance with Example H1. The reaction mixture is then stirred for 5 hours at a temperature of +25° C., in the course of which the product crystallizes out slowly. After the crystals have been separated off, washed with water and dried, 219 g (94.6%) of 2-benzylsulfinylphenylsulfonamide are obtained in the form of colourless crystals having a melting point of +206° to +209° C.
