Procedure

A mixture of N-(1-ethylpropyl)-2,6-dinitro-3,4-xylidine (50.0 g; 0.18 mol) and dimethylformamide dimethyl acetal (125 ml) is stirred at 85° C. overnight. The temperature of the reaction mixture is then raised to 90°-100° C. and methanol distilled off until approximately 12.5 ml methanol is collected. The reaction mixture is then cooled down, poured into hexane (400 ml) and chilled. The crystallized red solid (45.6 g; 75.3%) is collected and air dried. A sample is purified for analysis, melting point 100°-102° C.
