Reaction Steps
To a suspension of 2-(2,6-dimethyl-pyridin-4-yl)-5,7-difluoro-3H-quinazolin-4-one (0.72 g, 2.51 mmol) in DMF (10 mL), a solution of sodium methoxide in methanol (25 wt %, 1.36 g, 25.1 mmol) was added and the reaction mixture was stirred at room temperature for 16 hours. Water was added, the mixture was acidified to pH approximately 4-5 with acetic acid, and the precipitated solid was filtered and dried under vacuum, to give 2-(2,6-dimethyl-pyridin-4-yl)-7-fluoro-5-methoxy-3H-quinazolin-4-one as a light yellow solid. Yield: 0.28 g (37%).
