Abstract

An o-alkyl ether of an acylanilide is treated with chlorsulphonic acid to give the sulphonchloride, which is then reduced to the sulphinic acid. In an example acet-o-anisidide is treated with chlorsulphonic acid to give acet-o-anisidide-4-sulphonic chloride and it is then reduced with sodium sulphite which is maintained alkaline with caustic soda to give acet-o-anisidide-4-sulphinic acid. Acet-o-phenetidide may replace the acet-o-aniside.
