Procedure
A mixture of 1.88 g of 5-nitro-4,7-dimethyl-1,3-benzodioxole and 0.19 g of 10% palladium on carbon in 200 mL of ethanol is placed under a 50 psi hydrogen atmosphere. The mixture is shaken for 90 minutes at room temperature. The reaction mixture is filtered through Celite to yield a brownish solution. Concentration under reduced pressure affords 1.59 g of 5-amino-4,7-dimethyl-1,3-benzodioxole.
