Procedure

0.35 mol (76 g) of 2,6-dinitro-4-methylchlorobenzene is added gradually, in the course of 10 minutes, whilst stirring, to 150 ml of ethanolamine, the reaction medium being cooled as necessary so as not to exceed 75° C. When the addition has ended, the stirring is maintained for 5 minutes and the reaction medium is then poured into 600 g of iced water. The expected product precipitates. It is filtered off, washed with water and then recrystallised from ethanol. After drying in vacuo, it melts at 131° C.
