실험 절차

To a solution of N-[6-(3-aminophenoxy)imidazo[1,2-b]pyridazin-2-yl]cyclopropanecarboxamide (160 mg, 0.52 mmol) and 2,2,2-trichloroethyl (3-tert-butyl-1-phenyl-1H-pyrazol-5-yl)carbamate (200 mg, 0.52 mmol) in dimethylsulfoxide/water (2.0 mL/1.5 mL) was added triethylamine (53 mg, 0.52 mmol), and the mixture was stirred at 85° C. for 8 hr. The reaction mixture was diluted with ethyl acetate, washed with 1N hydrochloric acid, 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/hexane to give the title compound (285 mg, 99%) as a white powder.
