Improved method of S-alkylation of 2-mercaptobenzimidazole derivatives with trialkylphosphite

Abstract : A new method of S-alkylation of 2-mercaptobenzimidazole derivatives has been developed by the condensation of these heterocycles with trialkylphosphite in the presence of phosphorus oxychloride giving the corresponding 2-S-alkylbenzimidazoles. The structure of the obtained products has been established by spectroscopic data.
