実験手順

To a solution of N-[6-(5-amino-2-methoxyphenoxy)imidazo[1,2-b]pyridazin-2-yl]cyclopropanecarboxamide (150 mg, 0.44 mmol) in N-methylpyrrolidone (6.0 mL) was added 3-(trifluoromethyl)benzoyl chloride (92 mg, 0.44 mmol) under ice-cooling, and the mixture was stirred at room temperature for 12 hr. The reaction mixture was diluted with 1N hydrochloric acid and extracted with ethyl acetate, and the organic layer was washed with 5% aqueous sodium hydrogencarbonate solution and saturated brine, dried over anhydrous sodium sulfate, and filtrated. The solvent was evaporated under reduced pressure, and the residue was purified by NH silica gel column chromatography (ethyl acetate/hexane=50/50→100/0), and precipitated from ethyl acetate/diisopropyl ether to give the title compound (180 mg, 80%) as a white powder.
