Reaction Steps

A solution of 3-benzyloxy-6,7-difluoro-1H-quinazoline-2,4-dione (Example B, 3.0 g, 9.9 mmol) in 100 mL of DMF was added to a suspension of sodium hydride (0.47 g, 11.8 mmol) in 40 mL of DMF and stirred for 30 minutes. Ethyl iodide (7.9 mL, 99 mmol) was added, and the mixture was warmed to 50° C. for 18 hours. The reaction was quenched with 1 mL of water and concentrated to an oil. The residue was dissolved in chloroform washed with water, brine, and dried over magnesium sulfate. The solution was concentrated to give 3.2 g of the title compound as a solid, mp 133-135° C.
