Procedure

2.43 g (10 mmol) of -(3,4-dichlorophenyl)furan-2,5-dione and 1.08 g (10 mmol) of phenyl hydrazine in 50 ml of glacial acetic acid were boiled under ref lux for 5 h. The mixture was cooled and the product was then filtered off and washed first with glacial acetic acid and subquently with pentane. Yield: 1.8 g of a crystalline solid, m.p. 208-210° C.
