Reaction Steps

Palladium on carbon (10% Degussa Type) (100 mg, 0.94 mmol) was added to a stirring solution of 1-(1-(5-methoxy-2-methyl-4-nitrophenyl)piperidin-4-yl)-4-methylpiperazine (INTERMEDIATE 12, 697 mg, 2.00 mmol) in methanol (10 mL). The reaction mixture was then stirred under hydrogen (1 atm) at RT for 15 h. The reaction mixture was filtered through Celite® and the filtrate was concentrated in vacuo to give the title product which was used in the next step without further purification (566 mg, 66.1%). m/z 319.
