To a solution of N-(2-nitro-4-((4-phenylpiperazin-1-yl)methyl)phenylmethyl)acetamide (0.5 g) and water-containing Raney-nickel (0.5 g) in ethanol (8 ml) was added dropwise hydrazine monohydrate (0.7 ml) and the mixture was refluxed under heating at room temperature for 1 hr. Raney-nickel was removed by passing the mixture through Celite and the solvent was evaporated to give a white solid (0.48 g). The obtained white solid was crystallized from hexane/ethyl acetate (1:1, 100 ml) to give the title compound (45.5 g) as white crystals, m.p.=148-149° C.
