Reaction Steps
A solution of 2,4-dichloro-6-methoxyquinazoline (0.33 g) in methanol (5 mL) was added sodium methoxide (0.086 g), and the mixture was stirred at room temperature for 6 h. Water was added to the reaction mixture, and the aqueous layer was extracted with chloroform. The organic layer was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (silica gel, chloroform/methanol=50:1) to obtain 2-chloro-4,6-dimethoxyquinazoline (0.20 g).
