실험 절차

5,6-Dichloro-N-[2-(dimethylamino)ethyl]-N-methylpyridine-3-sulfonamide (104 mg, 0.33 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 under a nitrogen atmosphere at 100° C. for 2.5 hours. The reaction solution was cooled with ice, saline 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 amine-type silica gel column chromatography (Biotage NH, hexane:ethyl acetate:chloroform=2:5:1 to 2:5:2) to obtain the entitled compound (65 mg, yield: 61%) as a pale orange amorphous solid.
