Versuchsvorschrift

3-Chloro-N-[2-(dimethylamino)ethyl]-2-fluoro-N-methylisonicotinamide (116 mg, 0.45 mmol) and potassium tert-butoxide (70 mg, 0.62 mmol) were added to an N,N-dimethylacetamide solution (1 ml) of 4-[(1-methyl-1H-pyrazol-3-yl)amino]quinazolin-6-ol (650 mg, 0.25 mmol), and stirred under a nitrogen atmosphere at 80° C. for 2 hours. The reaction solution was cooled to room temperature, 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 to chloroform:methanol=1:3 to 100:2) to obtain the entitled compound (101 mg, yield: 84%) as a pale yellow amorphous solid.
