Versuchsvorschrift
1-methyl-4-(3-nitro-4-pyridyl)piperazine 14 (2.56 g, 11.52 mmol) in methanol (200 mL) was treated with palladium on carbon (10% wt % Degussa) (300 mg) and hydrogenated under balloon pressure at RT for 3 hours. The catalyst was filtered off and the filtrate was concentrated under reduced pressure to give 4-(4-methylpiperazin-1-yl)pyridin-3-amine 15 as a colourless solid (2.124 g, 11.05 mmol, 95.89%). MS (ES+) 193.1.
