To a solution of N-(2-nitrophenyl)-N',N'-dimethylethylenediamine (9.70 g) in methanol (50 ml) were added concentrated hydrochloric acid (8 ml) and 10% palladium-on-carbon (0.97 g) and the mixture was stirred under a hydrogen atmosphere at atmospheric pressure for 3.5 hours. The catalyst was filtered off and the filtrate was distilled off under reduced pressure to give 11.70 g of N-(2-aminophenyl)-N',N'-dimethylethylenediamine dihydrochloride.
