실험 절차

In a hydrogenation bottle, 130a (1.25 g, 5.73 mmol), EtOH (100 mL), 10% Pd/C (304 mmol, 0.286 mmol) were added. The mixture was hydrogenated at 55 psi for 2 hrs, filtered through celite, and washed with MeOH (20 mL). The solvent was removed in vacuo and off-white solids were obtained as 5-(1-methylpiperidin-4-yl)pyridin-2-amine 130b (1.13 g, 100%).
