Hydrochloric Acid → 2-Hydroxy-6-iodobenzenesulfonamide

Participants

Reaction Steps

0.50 g (1.60 mmol) of 2-iodo-6-methoxybenzenesulfonamide are introduced in 10 ml of dichloromethane at room temperature and this initial charge is cautiously admixed with 0.6 g (2.40 mmol) of boron tribromide. The reaction solution is stirred at room temperature for a further 45 min and then added to 2 N hydrochloric acid. Following extraction with dichloromethane, the organic phase is dried and evaporated. This gives 0.43 g (90% of theory) of 2-hydroxy-6-iodobenzenesulfonamide.
