실험 절차

To a stirred solution of 80 mg (0.278 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 4 ml of ethanol, 66 mg (0.417 mmol) of 3-methylcinnolin-5-amine was added. The resulting mixture was stirred at room temperature for one day. The final product was collected by filtration and purified by column chromatography (silica gel, ethyl acetate/hexane 2:1) to yield the title compound (65 mg, 58.6% yield).
