실험 절차

To a suspension of N-(5-{[2-(acetylamino)imidazo[1,2-b]pyridazin-6-yl]oxy}-2-methylphenyl)-1,3-dimethyl-1H-pyrazole-5-carboxamide (310 mg, 0.73 mmol) in methanol (10 mL) was added 4N hydrochloric acid/ethyl acetate (10 mL, 40 mmol), and the mixture was stirred at room temperature for 16 hr. The solvent was evaporated under reduced pressure, and the residue was washed with ethyl acetate/tetrahydrofuran, and then with diethyl ether to give the title compound (240 mg, 78%) as a pale-yellow solid.
