Procedure

With 15 ml of ethanol was mixed 0.8 g of N-[2-hydroxy-2-(4-nitrophenyl)ethyl]-2-nitro-N'-[3-(3-piperidinomethylphenoxy)propyl]-1,1-ethenediamine, and hydrogen gas was introduced thereinto in the presence of 0.1 g of 5% (by weight) palladium carbon at ordinary temperature and under atmospheric pressure for 7 hours until the absorption of hydrogen gas ceased. Subsequently, the catalyst was removed by filtration and the solvent was removed by distillation under reduced pressure. The resulting residue was purified by a column chromotography (Wako Silica Gel C-200, eluent; chloroform:methanol=5:1 by volume) to obtain 0.3 g (yield 40%) of amorphous N-[2-(4-aminophenyl)-2-hydroxyethyl]-2-nitro-N'-[3-(3-piperidinomethylphenoxy)propyl] -1,1-ethenediamine.
