실험 절차

(2S)-2-(tetrahydro-2H-pyran-2-yloxy)propyl methanesulfonate (214 mg, 0.90 mmol) and potassium tert-butoxide (200 mg, 1.8 mmol) were added to a dimethyl sulfoxide solution (5 ml) of 6-({4-[(1-methyl-1H-pyrazol-3-yl)amino]quinazolin-6-yl}oxy)pyridin-3-ol (300 mg, 0.90 mmol) obtained in Example 6-3), and the reaction solution was stirred for 24 hours at 100° C. The reaction solution was cooled to room temperature, then water and aqueous 1 N hydrochloric acid solution (0.9 ml, 0.9 mmol) were added, and extracted with ethyl acetate. The organic layer was washed with saturated saline water, then dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (chloroform:methanol=99:1) to obtain N-(1-methyl-1H-pyrazol-3-yl)-6-[(5-[(2R)-2-(tetrahydro-2H-pyran-2-yloxy)propyl]oxyl pyridin-2-yl)oxy]quinazoline-4-amine (322 mg, yield: 75%) as a pale brown solid.
