To a solution of 6-(3-aminophenoxy)-N-methylimidazo[1,2-b]pyridazine-2-carboxamide (250 mg, 0.88 mmol) in N,N-dimethylacetamide (2.5 mL) was added 1,3-dimethyl-1H-pyrazole-5-carbonyl chloride (253 mg, 1.59 mmol). After stirring at room temperature for 1 hr, water was added to the reaction mixture, and the precipitate was collected by filtration. The obtained residue was washed with water, acetonitrile and diethyl ether to give the title compound (262 mg, 73%) as a white powder.
