60 °C

0.2 mole (45.3 g) of 2,4,6-trichloronitrobenzene is added portionwise, with stirring, to 180 ml of N,N-diethylethylenediamine, heated to 60° C. After the end of the addition, heating is continued for 30 minutes. The reaction mixture is diluted with 180 ml of iced water. The expected product precipitates. It is filtered off, washed with water and then dried under vacuum at 60° C. in the presence of phosphorus pentoxide. After recrystallization from 96° ethanol, it melts at 90° C.
