Iodine chloride → 2-Amino-5-iodobenzenesulfonamide

Participants

Reaction Steps

To a cold (0° C.) stirred solution of 2-aminobenzenesulfonamide (17.2 g; 100 mmol) in CHCl3 (200 ml) was added a solution of iodine monochloride (17.1 g; 105 mmol) in CHCl3 (50 ml) over 1 h. The reaction mixture was slowly warmed up to rt. and left with stirring over night. The reaction mixture was filtered and the isolated solid was washed on the filter with CHCl3 (3×20 ml), NaHCO3 (sat. aq., 1×20 ml), H2O (4×50 ml). The isolated solid was air dried to give 27.3 g (92%) of product.
