Versuchsvorschrift

Alternate Procedure: A suspension of 2-sulfamoyl-4-methoxyfuro[3,2-c]pyridine (0.75 g, 3.3 mmol) in 10% aqueous hydrochloric acid (40 ml) was heated at 100° C. for 41/2 hours. Upon cooling, the product precipitated and was collected by filtration, washed with ethanol and diethyl ether to give 0.53 g (76% yield), m.p. 286°-289° C.
