Reaction Steps
388 mg of 4-[3-(4-benzyloxybenzoylamino)phenyl]-6,7-dimethoxy-2-methylaminoquinazoline obtained in Example 20 and 200 mg of 10% palladium-carbon powder (hydrate) were suspended in a mixed solvent of 10 ml ethyl acetate and 10 ml tetrahydrofuran. After the atmosphere was replaced with hydrogen, the mixture was stirred for 3 days at ordinary pressure at room temperature. The reaction solution was filtered, and the filtrate was evaporated. Then, the crude product was recrystallized from hexane-ethyl acetate to give 278 mg of the title compound as pale yellow crystals.
