実験手順

Ethyl [1-(3,4-dichlorobenzyl)piperidin-4-ylidene]acetate (3.9 g, 11.9 mmol) dissolved in tetrahydrofuran (25 ml) and ethanol (25 ml) was subjected to hydrogenation over platinum oxide (0.1 g) at ambient temperature and atmospheric pressure. The reaction mixture was filtered through a celite pad and concentrated in vacuo to give ethyl [1-(3,4-dichlorobenzyl)piperidin-4-yl]acetate (3.91 g) as a semi-solid.
