実験手順

To N-[5-({2-[(cyclopropylcarbonyl)amino]imidazo[1,2-b]pyridazin-6-yl}oxy)-2-fluorophenyl]-1,3-dimethyl-1H-pyrazole-5-carboxamide (225 mg, 0.5 mmol) were added tetrahydrofuran (5.0 mL) and ethanol (5.0 mL), dissolved at 70° C., and p-toluenesulfonic acid monohydrate (95 mg, 0.5 mmol) was added thereto. Ethanol (15.0 mL) was further added to the mixture and insoluble material was filtered off. The filtrate was concentrated, ethyl acetate (10 mL) and ethanol (10 mL) were added thereto, and the mixture was concentrated again. Ethyl acetate (10 mL) and ethanol (1.0 mL) were added thereto, and the mixture was stood at room temperature for 6 hr. The precipitated crystals were collected by filtration, washed successively with a small amount of ethanol and diethyl ether, and dried under reduced pressure at 80° C. for 6 hr to give the title compound (285 mg, 92%) as white crystals.
