実験手順
A solution of 7.6 g (0.023 mol) of 1-ethyl-4-[1-(phenylmethoxycarbonyl)-4-piperidinyl]piperidine in a mixture of 70 ml of methanol, 30 ml of water and 10 ml of glacial acetic acid was hydrogenated in the presence of 10% palladium/charcoal at room temperature and 3 bar of hydrogen pressure until the uptake of hydrogen had ceased. After working up in the usual way the desired compound was obtained as a colourless oil in a quantitative yield.
