Reaction Steps

The a solution of 1-[1-(3-methoxy-4-nitrophenyl)piperidin-4-yl]-4-methylpiperazine (0.3 g, 0.90 mmol) in 10 mL of ethanol purged with argon was added 10% Palladium on carbon (0.060 g). The hydrogenation was finished under 30 psi after 4 h. The mixture was passed through Celite to a flask containing HCl in ethanol. Concentration of the filtrate gave the final product (0.15 g, 88% yield). MS/ES+: m/z=334.
