Reaction Steps

0.3 mol (19.8 g) of 85% by weight potassium hydroxide pellets is dissolved in 210 ml of glycerol, and 0.25 mol (41.75 g) of 3,4-methylenedioxynitrobenzene is then added, with stirring. After heating for one and a half hours in the region of 110° C., the reaction medium is poured into 1.5 liters of iced water. The mixture is filtered in order to remove a small quantity of starting material. The filtrate is acidified to pH=4 with hydrochloric acid and then treated with 10 g of vegetable charcoal. After stirring for a few minutes at ambient temperature and removal of the vegetable charcoal by filtration, the solution is left to stand overnight at 0° C. and the expected product which has crystallized is then filtered off. After recrystallization from ethanol and drying in vacuo, the product melts at 148° C.
