実験手順

To a solution of N-[6-(3-amino-4-ethylphenoxy)imidazo[1,2-b]pyridazin-2-yl]cyclopropanecarboxamide (202 mg, 0.60 mmol) in N-methylpyrrolidone (3 mL) was added 1,3-dimethyl-1H-pyrazole-5-carbonyl chloride (143 mg, 0.90 mmol), and the mixture was stirred at room temperature for 8 hr. A 1N aqueous sodium hydroxide solution was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate/methanol=100/0→80/20) and recrystallized from a mixed solvent of ethyl acetate/diisopropyl ether to give the title compound (167 mg, yield 61%) as a white solid.
