Participants

Reaction Steps

To a flask, the 5-(tert-butoxycarbonylaminomethyl)furan-2-sulfonamide (5.2 g, 19 mmol) obtained above was added. 200 mL of a mixture of trifluoroacetic acid and dichloromethane (V/V=4:1) was then added to the flask. The reaction mixture was stirred at room temperature for 4 h. After the completion of the reaction, the reaction mixture was then concentrated to give 3.3 g (98.4% yield) of 5-(aminomethyl)furan-2-sulfonamide.
