80 °C

To a solution of 0.72 g (8.56 mmol) of NaHCO3 and 1.08 g (8.56 mmol) of Na2SO3 (4.6 mmol) in water (4.5 mL) are added 1 g (4.28 mmol) of 1,3-benzothiazol-6-sulfonyl chloride. The reaction is heated at 80° C. for 2 h. The solvent is removed under reduced pressure. The filtrate is concentrated under reduced pressure to give 1,3-benzothiazol-6-sulfinic acid sodium salt.
