실험 절차

2-(2,2-Diethoxyethoxy)-5-fluoropyrimidine (168 mg, 0.73 mmol) and potassium tert-butoxide (93 mg, 0.83 mmol) were added to an N,N-dimethylacetamide solution (1 ml) of 4-[(1-methyl-1H-pyrazol-3-yl)amino]quinazolin-6-ol (80 mg, 0.33 mmol), and stirred at 190° C. for 14 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=1:2) to obtain 6-{[2-(2,2-diethoxyethoxy)pyrimidin-5-yl]oxy}-N-(1-methyl-1H-pyrazol-3-yl)quinazoline-4-amine (56 mg, yield: 37%) as a pale brown amorphous solid.
