Reaction Steps

N-Benzyl-N-methyl-2-(1-(pyridin-4-yl)piperidin-4-yl)ethanamine (1.4 g, 3.63 mmol, 1 eq) was dissolved in MeOH (20 ml) and degassed for 30 min with nitrogen. 20% Pd—(OH)2 (200 mg) was added and hydrogenation was carried out for 2 h at RT under balloon pressure (H2). After monitoring by thin-layer chromatography, the reaction mixture was filtered off over Celite and washed with MeOH (3×25 ml), and the filtrate was concentrated under reduced pressure. Yield: 30% (240 mg, 1.09 mmol).
