Procedure

A solution of 2-(3-nitrophenyl)furan-3-carboxylic acid (1.2 g) in methanol (200 mL) containing concentrated sulfuric acid (5 drops) was heated under reflux for 18 h. The reaction solution was evaporated to dryness under reduced pressure to give the title compound as a yellow solid (0.66 g). m.p.=93–94° C.
