Procedure
2.6 g of 6-bromo-4-(5-diethoxymethylthiophen-2-yl)quinazoline (compound in Production Example 380) was dissolved in 10 mL dichloromethane, then 5 mL trifluoroacetic acid was added thereto, and the mixture was stirred at room temperature for 3 hours, neutralized by adding water and a sodium bicarbonate solution, and extracted with dichloromethane. The organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated, whereby 2.07 g of the title compound was obtained as pale yellow crystals.
