Reaction Steps

To a stirred solution of 250 mg (0.870 mmol) of 5-acetyl-2-ethyl-4-nitro-6-phenylpyridazin-3(2H)-one (Dal Piaz, V et al, J. Med. Chem. 1997, 40, 1417) in ethanol (12 mL), adenine (235 mg, 1.740 mmol) was added. The resulting mixture was stirred and refluxed during two days. The solvent was evaporated and the residue purified by column chromatography (silica gel, dichloromethane/methanol 95:5) and preparative HPLC/MS to yield the title compound (4.4 mg, 1.4% yield).
