46 g (264.1 mmol) 3-Phenyl-furan-2,5-dione were suspended in 1.56 L water. After addition of 34.4 g (264.1 mmol) hydrazine sulfate the reaction mixture was heated to reflux (bath temperature: 115° C.) and kept there for five hours. During the night the reaction mixture was kept at a bath temperature of 98° C. After cooling the precipitate was sucked off, washed with water (100 mL) and dried at 40° C. yielding 47.6 g (95.8%) of the title compound.
