60 °C

0.2 mole (45.3 g) of 2,4,6-trichloronitrobenzene is added in small portions to 180 ml of N,N-diethylethylenediamine heated to 60° C., with stirring. Heating is continued for 30 minutes after the addition is complete. The reaction medium is diluted with 180 ml of ice-cold water. The product expected precipitates. It is drained, washed with water and then dried under vacuum at 60° C. in the presence of phosphorous pentoxide. After recrystallizing from 96° ethanol, it melts at 90° C.
