Versuchsvorschrift
Into 30 ml. of concentrated sulfuric acid is added 2.85 grams of N-(ethoxycarbonyl)-3,4-dimethyl-2,6-dinitroaniline. The mixture is heated to a temperature in the range of from 110° C. to 120° C. for 15 minutes and then poured over ice. The precipitated solid is collected and crystallized from absolute ethanol yielding the desired product having a melting point of from 141.5° C. to 142.5° C.
