Reaction Steps

A suspension of 2.28 g (5.62 mmol) tert-butyl 4-(1-benzyl-4-methyl-piperidin-4-yl)-piperazine-1-carboxylate and 300 mg 10% Pd/C in 50 mL MeOH was hydrogenated for 3 h at 50° C. and 3447 hPa hydrogen pressure. To complete the reaction 0.47 mL conc. HCl were added and the mixture was hydrogenated for another 3 h at 50° C. and 3447 hPa hydrogen pressure. The catalyst was filtered off, the filtrate was evaporated down i. vac., the residue was stirred with diethyl ether, suction filtered and dried.
