実験手順

5,6-Dichloro-N-[2-(dimethylamino)ethyl]-N-methylnicotinamide (126 mg, 0.46 mmol) and potassium tert-butoxide (58 mg, 0.52 mmol) were added to an N,N-dimethylacetamide solution (1 ml) of 4-[(1-methyl-1H-pyrazol-3-yl)amino]quinazolin-6-ol (50 mg, 0.21 mmol), and stirred overnight under a nitrogen atmosphere at 130° C. The reaction solution was cooled with ice, saline water was added, and extracted with chloroform. The organic layer was washed with water, then dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The obtained residue was purified by amine-type silica gel column chromatography (Biotage NH, hexane:ethyl acetate to chloroform:methanol=1:4 to 100:2) to obtain the entitled compound (25 mg, yield: 25%) as a pale yellow solid.
