Reaction Steps
To a suspension of 5,7-difluoro-2-pyridin-4-yl-3H-quinazolin-4-one (0.20 g, 0.80 mmol) in DMF (3 mL) was added sodium methoxide in methanol (0.43 g, 8.0 mmol) and the reaction mixture was stirred at room temperature for 16 hours. Water was added, the mixture was acidified with acetic acid to pH approximately 4-5, and the precipitated solid was filtered off to obtain 7-fluoro-5-methoxy-2-pyridin-4-yl-3H-quinazolin-4-one as a yellowish solid. Yield: 0.20 g (83%).
