A mixture of ethyl 6-(3-{[3-(trifluoromethyl)benzoyl]amino}phenoxy)imidazo[1,2-b]pyridazine-2-carboxylate (470 mg, 1.00 mmol), 8N aqueous sodium hydroxide solution (2.0 mL) and methanol (6.0 mL) was stirred at room temperature for 4 hr. 6N Hydrochloric acid (2.7 mL) and water (25 mL) were added to the mixture, and the mixture was extracted with ethyl acetate (50 mL). The extract was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to give the title compound (425 mg, 96%) as a white powder.
