実験手順

2,3-Dichloro-5-(2,2-diethoxyethoxy)pyridine (641 mg, 2.29 mmol) and potassium tert-butoxide (279 mg, 2.49 mmol) were added to an N,N-dimethylacetamide solution (3 ml) of 4-[(1-methyl-1H-pyrazol-3-yl)amino]quinazolin-6-ol (240 mg, 1.00 mmol), and stirred at 170° C. for 14 hours under a nitrogen atmosphere in a sealed tube. The reaction solution was cooled with ice, then saline water and chloroform were added, the organic layer was washed with water, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was purified by reversed-phase liquid chromatography (YMC CombiPrep Pro C18 AS-360-CC) to obtain 6-{[3-chloro-5-(2,2-diethoxyethyl)pyridin-2-yl]oxy}-N-(1-methyl-1H-pyrazol-3-yl)quinazoline-4-amine (217 mg, yield: 45%) as an orange oil and 6-{[2-chloro-5-(2,2-diethoxyethoxy)pyridin-3-yl]oxy}-N-(1-methyl-1H-pyrazol-3-yl)quinazoline-4-amine (136 mg, yield: 28%) as an orange oil.
