Vorschrift

A mixture comprising 0.18 mole (50 g) of 2,4-dinitro 1,3,5-trichlorobenzene and 250 ml of dioxane are heated at 70° C. 0.64 mole (219.9 g) of sodium ethylate in solution at a concentration of 20% in ethanol are then added while agitating. After the end of the addition the agitation is continued two more hours at 70° C. The reaction mixture is cooled and diluted with iced water. The expected product crystallizes and is separated by filtration. After drying it is recrystallized from ethanol. It melts at 105° C.
