Procedure
10 g (40.9 mmol) 3-(1-benzylpiperidin-4-yloxy)-propionitrile are dissolved in 100 ml ethanol and added to a spatula tip Raney-Nickel. The mixture is stirred at RT and under hydrogen atmosphere until the consumption of the theoretical amount of hydrogen to be taken up (ca. two days). Subsequently, this is filtered from the catalyst and the solvent is removed under vacuum. The residue is distilled in a bulb tube apparatus. Yield of a colorless oil: 7.5 g (73%).
