Vorschrift

0.05 mol (10.6 g) of 4,5-methylenedioxy-1,2-dinitrobenzene is added to 40 ml of a 33% strength solution of methylamine in absolute ethanol to which 20 ml of 96° strength ethanol have been added. The reaction edium is heated under reflux for 30 minutes. After dilution with 150 ml of ice-cold water, the expected product precipitates. After being drained and washed with water, it is recrystallized from a mixture of ethanol and acetone. It melts at 170° C. (literature 171° C.).
