Reaction Steps

Methanol (5 ml) and sodium hydroxide (0.2 g) were added to 4-[(6,7-dimethoxy-4-quinazolinyl)oxy]phenyl benzoate (500 mg), and the mixture was stirred at 0° C. for 30 min. A saturated aqueous ammonium chloride solution was added to the reaction solution, and the mixture was extracted with chloroform, followed by washing with saturated brine. The extract was then dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure. Methanol was added to the residue, and the precipitated crystal was collected by filtration and was washed to give the title compound (350 mg, yield 95%).
