Versuchsvorschrift
A mixture of 74.9 g. (0.25 mole) of 2,4-dichloro-3,5-dinitrobenzoyl chloride and 200 ml. of concentrated ammonia is placed in a mortar and ground with a pestle for ten minutes. The mixture stands for two hours at room temperature. The yellow precipitate is removed by filtration and washed with water. There is obtained 67.7 gm. (97%) of yellow needles melting at 263°-265°. Recrystallization of 1.00 g. of material from ethanol yields 390 mg. of yellow needles melting at 262°-263°.
