실험 절차

To a solution of N-[6-(3-amino-4-fluorophenoxy)imidazo[1,2-b]pyridazin-2-yl]cyclopropanecarboxamide (200 mg, 0.61 mmol) in N,N-dimethylformamide (4.0 mL) were added 1,5-dimethyl-1H-pyrazole-3-carboxylic acid (171 mg, 1.22 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (351 mg, 1.83 mmol), 1-hydroxybenzotriazole (248 mg, 1.83 mmol) and triethylamine (256 μL, 1.83 mmol), and the mixture was stirred at 60° C. for 36 hr. 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 obtained residue was purified by silica gel column chromatography (ethyl acetate/hexane=3/1→ethyl acetate alone) to give the title compound (72 mg, 26%) as a white powder.
