Versuchsvorschrift

A mixture of 2,6-dichloro-4-trifluoromethylphenylhydrazine (1.0 g) and fumaronitrile (1.0 g) in dimethylsulfoxide (10 ml) was heated at 100° C. for 7 hours. The cooled mixture was diluted with water and extracted (ether) to give, after evaporation and crystallization from dichloromethane/hexane, the title compound (0.828 g, 63%), m.p. 101-102° C.
