A solution of 40 g of 2-(1-benzyl-4-heptyl-4-piperidyloxy)-ethanol in 300 ml of absolute ethanol was reacted with hydrogen at 50° C in the presence of 0.4 g of 5% palladized charcoal until the theoretical amount of hydrogen was absorbed and the catalyst was then filtered off. The ethanol was distilled off and the residue was rectified to obtain 10.6 g of 2-(4-heptyl-4-piperidyloxy)-ethanol as a colorless oil boiling at 110°-130° C at 0.1 mm Hg.
