Versuchsvorschrift

Nitric acid (30 ml) is cooled to -5°, and N-methylcarbonyl 2,3-dichloroaniline (9.8 g, 48 mmol) is added to the acid in small portions, with the temperature maintained at -5° or lower. After the addition is complete, the reaction is stirred for 1 hour at +5°. The reaction is then added dropwise to about 150 g of ice-water mixture. The resulting solid is collected by filtration and purified by prep. TLC (developing with 30% ethyl acetate/hexane). The least polar component is isolated to give N-methylcarbonyl 2,3-dichloro-6-nitroaniline.
