実験手順

A mixture of 14.8 parts of N-{4-(methoxymethyl)-1-[2-(4-nitrophenyl)ethyl]-4-piperidinyl}-N-phenylpropanamide and 200 parts of methanol is hydrogenated at normal pressure and at room temperature with 3 parts of Raney-nickel catalyst. After the calculated amount of hydrogen is taken up, the catalyst is filtered off and the filtrate is evaporated. The oily residue is purified by column-chromatography over silica gel using a mixture of trichloromethane and 5% of methanol as eluent. The pure fractions are collected and the eluent is evaporated. The oily residue is triturated in petroleumether. The product is filtered off and crystallized from a small amount of 2,2'-oxybispropane. It is filtered off and dried, yielding 8.23 parts of N-{1-[2-(4-aminophenyl)ethyl]-4-(methoxymethyl)-4-piperidinyl}-N-phenylpropanamide; mp. 106.2° C.
