Water → 2-Iodo-6-propoxybenzenesulfonamide

Participants

Reaction Steps

5.00 g (16.72 mmol) of 2-hydroxy-6-iodobenzenesulfonamide are introduced in 50 ml of dimethylformamide and this initial charge is admixed with 2.54 g (18.39 mmol) of potassium carbonate. This mixture is stirred at room temperature for 1 h. Thereafter 3.13 g (18.39 mmol) of propyl iodide are added dropwise and the reaction mixture is stirred at room temperature for 3 h. It is then poured into water, and the product precipitates out. The solid is washed with water and dried. This gives 4.00 g (70% of theory) of 2-iodo-6-propoxybenzenesulfonamide.
