Reaction Steps

Pyrrolidine (0.07 mL, 0.8 mmol) was added to a solution of 6,7-difluoro-3-hydroxy-1-methyl-1H-quinazoline-2,4-dione (Example L, 0.15 g, 0.66 mmol) and triethylamine (1.2 mL, 8.6 mmol) in 30 mL of acetonitrile. The solution was warmed to reflux for 18 hours, cooled, and filtered to give a solid. The solid was triturated with chloroform, filtered, and dried to give 0.07 g of the title compound as a solid, mp >250° C.
