Reaction Steps

5 g (0.23 mole) of 4,5-methylenedioxy-2-nitrobenzoic acid are suspended in 50 ml of thionyl chloride and refluxed for 2 hours. The solution obtained is concentrated under reduced pressure. The residual oil crystallizes immediately after the addition of 50 ml of petroleum ether. The crystals are spun and recrystallized in ether.
