Versuchsvorschrift
A mixture of 0.54 g (1.2 mmols) of 2-ethoxy-4-[N-{1-(2-piperidino-phenyl)-1-butyl}-aminocarbonylmethyl]-benzyl chloride (melting point 114°-115° C., prepared from 2-ethoxy-4-[N-{1-(2-piperidino-phenyl)-1-butyl}-aminocarbonylmethyl-benzyl alcohol and thionyl chloride in chloroform) and 10 ml of absolute dioxane was hydrogenated for 3 hours at 20° C. and a pressure of 5 bar hydrogen. The reaction mixture was then evaporated in vacuo, and the residue was taken up in a mixture of ethyl acetate and aqueous sodium carbonate. The organic phase was dried, filtered and evaporated in vacuo. The evaporation residue was purified by column chromatography on silica gel (chloroform/acetone=19/1).
