Vorschrift

0.05 mol (10.6 g) of 4,5-methylenedioxy-1,2-dinitrobenzene is added to 40 ml n-butylamine. The reaction is exothermic. The boiling point of butylamine is reached. As soon as the exothermic effect has finished, 200 g of ice are added to the reaction medium. After neutralization of the excess butylamine with concentrated hydrochloric acid, the expected product crystallizes. After recrystallization from 96° strength ethanol or from ethyl acetate, it melts at 137° C. (literature 137° C.).
