実験手順

To a solution of 1-({[6-(3-{[(1,3-dimethyl-1H-pyrazol-5-yl)carbonyl]amino}-4-methylphenoxy)imidazo[1,2-b]pyridazin-2-yl]amino}carbonyl)cyclopropyl acetate (130 mg, 0.25 mmol) in tetrahydrofuran (2 mL) was added 1N aqueous sodium hydroxide solution (2 mL), and the mixture was stirred at room temperature for 2 hr. 1N Hydrochloric acid (2.5 mL) and ethyl acetate were added to the reaction mixture, and the aqueous layer was extracted with ethyl acetate (×3). Combined organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and filtrated. The filtrate was concentrated under reduced pressure, and the residue was washed with ethyl acetate/hexane to give the title compound (99 mg, 86%) as a pale-yellow solid.
