Procedure

To a solution of 0.81 g of NaHCO3 (9.61 mmol) and 1.21 g of Na2SO3 (9.61 mmol) in water (10 mL) was added 1 g (4.7 mmol) of 6-chloro-pyridine-3-sulfonyl chloride. The reaction was heated at 80° C. for 3 h. The solvent was removed under reduced pressure. The filtrate was concentrated under reduced pressure to give 6-chloro-pyridine-3-sulfinic acid sodium salt.
