Versuchsvorschrift
To a stirred solution of 80 mg (0.278 mmol) of 5-acetyl-2-ethyl-4-nitro-phenylpyridazin-3(2H)-one (Dal Piaz, V et al, J. Med. Chem. 1997, 40, 1417) in 4 ml of ethanol, 60 mg (0.417 mmol) of 5-isoquinolinamine was added. The resulting mixture was stirred at room temperature for three days. The final product was collected by filtration and purified by column chromatography (silica gel, ethyl acetate/hexane 7:3) to yield the title compound (20 mg, 12.4% yield).
