反应详情

To a solution of N-(4-nitrophenyl)piperidine (12 g) in methanol (50 ml) was added conc. hydrochloric acid (12 ml) and, by using 10% palladium/carbon as a catalyst, catalytic reduction was conducted at normal temperature and normal pressure. After completion of the reaction, the catalyst was removed and the solvent was distilled off. To the residue was added ethyl ether which was filtered off to obtain N-(4-aminophenyl)piperidine dihydrochloride (13.7 g) as a colorless solid.
