—— | p-nitro-m-methylbenzenesulfonyl chloride | 78726-75-7 | C7H6ClNO4S | 235.648 |
The 4-, 5-, 6-, and 7-mercaptoindoles have been prepared via the Reissert condensation of the isomeric benzylthio-o-nitrotoluenes. The latter were synthesized by diazotization of the corresponding 2-nitrotoluidines or by direct displacement of the halogen atom in monobrominated o-nitrotoluenes with the benzylmercapto group using dimethylformamide as solvent.
