Procedure

With cooling with ice, sodium borohydride (9 mg, 0.25 mmol) was added to a tetrahydrofuran (3 ml)/water (0.3 ml) mixed solution containing {[5-chloro-6-({4-[(1-methyl-1H-pyrazol-3-yl)amino]quinazolin-6-yl}oxy)pyridin-3-yl]oxy}acetaldehyde obtained in Example 1, and the reaction solution was stirred for 15 minutes. Saturated saline water was added to the reaction solution, extracted with chloroform/methanol (9:1), the organic layer was dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (Biotage, chloroform:methanol=100:4 to 100:5) and reversed-phase liquid chromatography (YMC CombiPrep Pro C18 AS-360-CC), and the obtained solid was recrystallized from ethyl acetate to obtain the entitled compound (19 mg) as a white solid.
