Reaction Steps

To a stirring solution of 1-methyl-4-(3-nitro-pyridin-2-yl)-piperazine (LXXXIII) (1.30 g, 5.85 mmol) in MeOH (15 mL) was added 10% Pd/C. The solution was purged with hydrogen. The solution was stirred at room temperature for 16 h under hydrogen. The solution was filtered through a pad of Celite and concentrated to a residue under vacuum. The residue was purified by column chromatography (100% CHCl3→2:98 MeOH[7N NH3]:CHCl3) to afford 2-(4-methylpiperazin-1-yl)pyridin-3-amine (LXXXIV) (0.466 g, 2.42 mmol, 52% yield) as a tan solid. ESIMS found for C10H16N4 m/z 192.4 (M+H).
