To a solution of N-(2-nitrophenyl)-N',N'-dimethylethylenediamine (149.2 g) in methanol (1500 ml) were added concentrated hydrochloric acid (60 ml) and 10% palladium-on-carbon (15 g). The reaction mixture was stirred under a hydrogen atmosphere at atmospheric pressure for 5.5 hours. The reaction mixture was then filtered and concentrated under reduced pressure to give 149.2 g of N-(2-aminophenyl)-N',N'-dimethylethylenediamine hydrochloride.
