Procedure
To a suspension of.3-cyano-3-(3-nitro-phenyl)-acrylic acid potassium salt (1.28 g) in formic acid (10 ml) and water (1 ml) was added sulfuric acid (1 ml), and the mixture was refluxed for 3 hours. After cooling, the mixte was poured into water. The resulting precipitate was collected by filtration and dried to give 3-(3-nitrophenyl)-furan-2,5-dione(0.69 g).
