Procedure

A suspension of 0.44 g (1.10 mmol) ethyl[4-(1-benzyl-4-methyl-piperidin-4-yl)-piperazin-1-yl]-acetate and 100 mg 10% Pd/C in 20 mL EtOH was hydrogenated for 12 h at 50° C. and 3447 hPa hydrogen pressure. The catalyst was filtered off and the filtrate was evaporated to dryness. The product was reacted further without purification.
