Reaction Steps

A quantity of 0.46 gm (1 mmol) of 4-[(1-(2-piperidino-phenyl)-ethyl)-aminocarbonylmethyl]-benzoic acid benzyl ester in 20 ml of ethanol was hydrogenated at 0.25 gm of palladium/charcoal at 50° C. and a hydrogen pressure of 5 bar. After five hours the catalyst was filtered off over celite, and the filtrate was evaporated in vacuo. The evaporation residue was recrystallized from ethanol/water (8:2).
