Reaction Steps

0.48 g (0.00135 mol) of 1-(4-nitro-benzyl)-piperidin-4-yl 4-methyl-benzoate was dissolved in 27 ml of ethanol and treated with 0.48 g of Raney-nickel. The mixture was hydrogenated at room temperature and under normal pressure for 3 hrs. The catalyst was filtered off and, after concentration, the residue was chromatographed on silica gel with ethyl acetate/hexane (1:1→5:2) as the eluent. 0.405 g (92.5%) of 1-(4-amino-benzyl)-piperidin-4-yl 4-methyl-benzoate was obtained as a yellowish oil. MS: me/e=325 (C20H25N2O2+).
