Reaction Steps

A mixture of 27 parts of (4-fluorophenyl) [1-{3-[(2-nitrophenyl)amino]propyl}-4-piperidinyl]methanone in 400 parts of methanol is hydrogenated at normal pressure and at room temperature with 5 parts of Raney-nickel catalyst. After the calculated amount of hydrogen is taken up, the catalyst is filtered off over hyflo and the filtrate is evaporated, yielding 25 parts (100%) of [1-{3-[(2-aminophenyl)amino]-propyl}-4-piperidinyl] (4-fluorophenyl)methanone as a residue.
