実験手順

2-Chloro-5-(2,2-diethoxyethoxy)pyrimidine (225 mg, 0.91 mmol) obtained in Example 7 and potassium tert-butoxide (116 mg, 1.04 mmol) were added to an N,N-dimethylacetamide solution (1 ml) of 4-[(1-methyl-1H-pyrazol-3-yl)amino]quinazolin-6-ol (100 mg, 0.42 mmol), and stirred at 200° C. for 18 hours under a nitrogen atmosphere in a sealed tube. The reaction solution was cooled with ice, water was added, and extracted with chloroform. The organic layer was washed with water, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (Moritex, acetone:hexane=2:3) to obtain 6-{[5-(2,2-diethoxyethoxy)pyrimidin-2-yl]oxy}-N-(1-methyl-1H-pyrazol-3-yl)quinazoline-4-amine (177 mg, yield: 95%) as a pale orange amorphous solid.
