실험 절차

To a solution of (6-iodoimidazo[1,2-b]pyridazin-2-yl)methanol (400 mg, 1.45 mmol) in N,N-dimethylformamide (4.0 mL) were added N-(3-hydroxyphenyl)-1,3-dimethyl-1H-pyrazole-5-carboxamide (504 mg, 2.18 mmol) and potassium carbonate (402 mg, 2.91 mmol), and the mixture was stirred at 150° C. for 16 hr. After cooling the mixture to room temperature, water was added to the reaction mixture, and the mixture was extracted with ethyl acetate/tetrahydrofuran, washed with saturated brine, dried over anhydrous sodium sulfate, and filtrated. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate/ethanol=100/0→10/1) to give the title compound (70 mg, 13%) as a white powder.
