Reaction Steps
Twenty percent Pd/C (0.2 g) was added to a solution of 3-benzyloxy-6,7-difluoro-1-methyl-1H-quinazoline-2,4-dione (Example K, 1.55 g, 4.9 mmol) in 25 mL of THF and 25 mL of methanol. The mixture was shaken under 50 PSI of hydrogen for 1.5 hours, and filtered. The catalyst was rinsed with 200 mL of a 50/50 mixture of THF and methanol and concentrated to afford 1.1 g of the title compound as a solid, mp 239-241° C.
