Reaction Steps

A mixture of 8 parts of N-(4,5-dichloro-2-nitrophenyl)-4-(diphenylmethyl)-1-piperazinepropanamine and 200 parts of methanol is hydrogenated at normal pressure and at room temperature with 2 parts of Raney-nickel catalyst. After the calculated amount of hydrogen is taken up, the catalyst is filtered off and the filtrate is evaporated, yielding 4,5-dichloro-N1 -{3-[4-(diphenylmethyl)-1-piperazinyl]propyl}-1,2-benzenediamine as an oily residue.
