Versuchsvorschrift

3,5-Dimethyl-4-nitro-I,2-(methylenedioxy)benzene (5.0 g) and 10% palladium on charcoal catalyst (1.2 g) in ethanol (250 ml) was shaken in a hydrogen atmosphere (50 p.s.i.) at 40° C. for 4 hours. The mixture was filtered through celite and evaporated to leave 2,6-dimethyl-3,4-(methylenedioxy)aniline (2.8 g, 68%) as a dark oil.
