Participants

Reaction Steps

A mixture of 3-benzylthio-4-chloro-5-sulfamylbenzoic acid (0.75 g), acetic acid (25 ml), and hydrogen peroxide (2 ml of an 30% aqueous solution) is stirred for 2 days at room temperature. Addition of water (100 ml) precipitates 3-benzylsulfonyl-4-chloro-5-sulfamylbenzoic acid. After collection by filtration and recrystallization from aqueous ethanol the compound crystallizing with one mole of water, is obtained with a melting point of 236° - 237° C.
