実験手順

(1S)-2-{[tert-butyl(dimethyl)silyl]oxy}-1-methylethyl methanesulfonate (79 mg, 0.29 mmol) and potassium tert-butoxide (55 mg, 0.49 mmol) were added to a dimethyl sulfoxide solution (3 ml) of 5-chloro-6-({4-[(1-methyl-1H-pyrazol-3-yl)amino]quinazolin-6-yl}oxy)pyridin-3-ol (90 mg, 0.24 mmol) obtained in Example 22, then stirred for 24 hours at 100° C. The reaction solution was cooled to room temperature, water was added, and extracted with ethyl acetate. The organic layer was washed with saturated saline water, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=1:2 to 0:1) to obtain 6-{[5-((1R)-2-{[tert-butyl(dimethyl)silyl]oxy}-1-methylethoxy)-3-chloropyridin-2-yl]oxy}-N-(1-methyl-1H-pyrazol-3-yl)quinazoline-4-amine (43 mg, yield: 33%) as a white solid.
