Procedure

To a suspension of 2-sulfamoylfuro[3,2-b]pyridine (647 mg, 3.27 mmol) in glacial acetic acid (8 mL) was added 30% hydrogen peroxide (0.6 mL). This suspension was warmed at 60° C. for four hours to give a clear solution. Upon cooling the reaction mixture and adding water the product crystallized out. This pure product (444 mg, 63.5% yield) was collected by filtration, washed with water, ethanol and diethyl ether, mp: 236°-237° C. (decomposition).
