実験手順

To a solution of N-{6-[(3-aminophenyl)sulfanyl]imidazo[1,2-b]pyridazin-2-yl}cyclopropanecarboxamide (195 mg, 0.6 mmol) in N-methylpyrrolidone (3.0 mL) was added 1,3-dimethylpyrazole-5-carbonyl chloride (159 mg, 1.0 mmol), and the mixture was stirred at room temperature for 18 hr. The reaction mixture was diluted with water, and 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→70/30) and precipitated from methanol to give the title compound (245 mg, 91%) as a white powder.
