Participants

Reaction Steps

After a mixture of 5-isoquinolinesulfonyl chloride 1.58 g (7.0 mmol), sodium sulfite 880 mg (7.0 mmol) and water 10 ml was heated and refluxed for 1 hour, the reaction mixture was concentrated under reduced pressure. Ethanol was added to the resulting residue to filter off insoluble materials, and the filtrate was concentrated under reduced pressure to give sodium 5-isoquinolinesulfinate 375 mg (25.0%).
