Procedure

A mixture of 10.04 g. (0.04 mole) of 2,4-dichloro-3,5-dinitrotoluene, 5.85 g. (0.08 mole) of sec-butylamine and 200 ml. of cyclohexane is stirred at reflux for six hours. The mixture is filtered and the filtrate is evaporated at reduced pressure. The filtrate is partitioned between ether and dilute hydrochloric acid. The organic phase is washed with water and brine, dried over magnesium sulfate and evaporated in vacuo. Crystallization of the residue from ethanol gives 7.71 g. of orange crystals, m.p. 40°-46° C. Two recrystallizations from ethanol give the analytical sample, m.p. 45°-47° C. Analysis Calcd. for C11H14ClN3O4 : C, 45.92; H, 4.90; Cl, 12.32; N, 14.61. Found: C, 45.96; H, 4.97; Cl, 12.36; N, 14.78.
