Procedure

Twenty percent Pd/C was added to a solution of 3-benzyloxy-1-ethyl-6,7-difluoro-1H-quinazoline-2,4-dione (Example C, 0.055 g, 0.16 mmol) in 25 mL of THF and 25 mL of methanol. This was shaken under 50 PSI of hydrogen for 12.5 hours. The mixture was filtered and concentrated to afford 0.03 g of the title compound as a solid, mp 172-174° C.
