Reaction Steps

To a stirred solution of 40 mg (0.139 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 (4 mL), 8-amino-5-bromoquinoline (47 mg, 0.209 mmol) was added. The resulting mixture was stirred at room temperature for five days and heated at 50° C. during four days. The solvent was evaporated and the residue purified by column chromatography (silica gel, hexane/ethyl acetate 4:1) to yield the title compound (16 mg, 25% yield).
