実験手順: 10% Palladium on carbon (115 mg, 10% by wt.) was placed under an inert atmosphere and suspended in EtOH (5 mL). A solution of 2-(4-benzyl-piperazin-1-yl)-N-methyl-acetamide (1.15 g, 4.65 mmol) dissolved in EtOH (18 mL) was added. The reaction mixture was placed under H2 atmosphere (1 Atm pressure) and stirred overnight. The resulting mixture was filtered through a pad of Celite® and the solvent was concentrated in vacuo to give 723 mg (98.9%) of the title compound as a white solid. 1H-NMR (300 MHz, DMSO-d6) 7.61 (broad s, 1H), 2.80 (s, 2H), 2.68 (t, 4H), 2.59 (d, 3H), 2.31 to 2.26 (m, 4H); ES-MS m/z 158.0 [M+H]+, RT (min) 1.13. was added The resulting mixture was filtered through a pad of Celite® the solvent was concentrated in vacuo
