Two methods for the synthesis of (indol-3-yl)methanesulfonamide were elaborated based on the ‘switching off’ the reactivity of the indole nucleus in the intermediates by using indoline or indoxyl compounds. (2,3-Dihydroindol-3-yl)methanesulfonic acid was the key compound used in the indole-indoline approach and (1-acetyl-3-hydroxy-2,3-dihydroindol-3-yl)-N-(tert-butyl)methanesulfonamide was the key intermediate when 1-acetylindoxyl was used as the starting compound.
