Versuchsvorschrift

0.13 mole (30.6 g) of 2,4,5-trichloronitrobenzene is added to a solution of 78 g of ethylenediamine in 100 ml of 96° ethanol and 117 ml of water. After heating under reflux for 1 h 30 min, the reaction mixture is cooled. After dilution with iced water, the expected product precipitates. It melts as 84° C.-87° C.
