実験手順

To a solution of 0.39 g of NaHCO3 (4.6 mmol) and 0.58 g of Na2SO3 (4.6 mmol) in water (2.5 mL) were added 0.5 g (2.3 mmol) of 3-pyridinesulfonyl 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 3-pyridylsulfinic acid sodium salt.
