Versuchsvorschrift

A mixture of 2-(4-formylphenyl)furan (0.335 g, 1.95 mmol, prepared according to the method of Heterocycles, 1990, 31, 1951), sulfanilamide (0.336 g, 1.95 mmol) in ethanol (8 mL) was heated at reflux temperature for 2.5 hour. After cooling to room temperature, the crystals which collected by filtration and washed with ethanol to give the subtitle compound (0.378 g).
