Reaction Steps
A mixture of ethyl 2,5-dioxo-3-(3-nitrophenyl)-5-phenylpentanoate (1.5 g) and hydrazine monohydrate (0.24 g) in ethanol (30 ml) was refluxed for 5.5 hours. After evaporating the solvent in vacuo, the residue was subjected to a column chromatography on silica gel (100 ml) eluting with a mixture of benzene and ethyl acetate (50:1 V/V). The fractions containing the object compound were combined and concentrated under reduced pressure to give ethyl 1,4-dihydro-4-(3-nitrophenyl)-6-phenyl-3-pyridazinecarboxylate (0.52 g).
