Reaction Steps
A suspension of 1-(4-iodophenyl)-3-(1-phenyl-1H-pyrazol-5-yl)furo[3,2-c]pyridazin-4(1H)-one (200 mg), pyrazole (57 mg), copper oxide (6 mg), 2-hydroxybenzaldehydeoxime (23 mg) and cesium carbonate (271 mg) in DMF (5 mL) was stirred at 50° C. for 12 hr, and water was added. The reaction mixture was extracted with ethyl acetate, the extract was washed with saturated brine, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (methanol/ethyl acetate) to give the title compound (64 mg).
