Versuchsvorschrift

A mixture of 2-methoxy-1,3-dinitro-benzene (1.49 g) and palladium on carbon (10%, 150 mg) in ethanol (75 mL) was stirred under hydrogen atmosphere (1 atm.) overnight. The catalyst was filtered off on a CELITE™ pad and the filter cake was washed with ethanol. The filtrate was evaporated under reduced pressure to afford 1.1 g of 2-methoxy-benzene-1,3-diamine as a light yellow solid without further purifications.
