42.40 g (114.84 mmol) N-(tert-butyl)-2-iodo-6-methoxybenzenesulfonamide are stirred in 265 ml of trifluoroacetic acid at room temperature for 3 h. Thereafter the reaction mixture is poured into ice-water and the precipitate is isolated by filtration and washed to neutrality with water. This gives 32.40 g (90% of theory) of 2-iodo-6-methoxybenzenesulfonamide.
