実験手順: 10.0 g (40.9 mmol) 3-(1-benylpiperidin-4-yloxy)-propionitrile are dissolved in 100 ml ethanol and added to a spatula tip of Raney-Nickel. The mixture is stirred at RT under hydrogen atmosphere until the uptake of the theoretical amount of hydrogen (ca. two days). The mixture is filtered from the catalyst and the solvent is removed under vacuum. The residue is distilled in a bulb tube apparatus. Yield of colorless oil: 7.5 g (73%). The mixture is filtered from the catalyst the solvent is removed under vacuum The residue is distilled in a bulb tube apparatus

実験手順: 2.4 g (16.2 mmol) 3-(3-pyridyl)-acrylic acid and 2.3 ml (16.2 mmol) TEA are suspended in 50 ml abs. toluene and a solution of 1.5 ml (15.5 mmol) chloroformic acid ethyl ester in 20 ml abs. toluene are added dropwise under moisture exclusion and light cooling. This yellow suspension is stirred at RT for two hours and then a solution of 3.5 g (14.1 mmol) 3-(1-benzylpiperidin-4-yloxy)-propylamine in 20 ml abs. toluene is added dropwise. The mixture is stirred for two hours at RT and extracted by shaking three times in the heat, each with 10 ml water, 2 M sodium hydroxide and water again. The organic phase is concentrated under vacuum and the orange colored oily residue is chromatographically purified twice over silica gel with CHCl3/CH3OH/NH4OH (90/9/1 and 95/5/0 to 90/10/0) and crystallized from 10 ml acetic acid ethyl ester. Colorless crystals remain with a MP of 100–102° C.; yield: 1.9 g (35%). cooling The mixture is stirred for two hours at RT extracted by shaking three times in the heat The organic phase is concentrated under vacuum the orange colored oily residue is chromatographically purified twice over silica gel with CHCl3/CH3OH/NH4OH (90/9/1 and 95/5/0 to 90/10/0) crystallized from 10 ml acetic acid ethyl ester

実験手順: 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%).
