Procedure

Twenty percent Pd/C (25 mg) was added to a solution of 3-benzyloxy-1-(2-fluoroethyl)-6-fluoro-7-pyrrolidin-1-yl-1H-quinazoline-2,4-dione (Example E-4, 0.17 g, 0.4 mmol) in 50 mL of THF, this was shaken under 50 PSI of hydrogen for 14.5 hours. The mixture was filtered and concentrated to afford 0.16 g of a solid, which was triturated with ether and dried to give 0.07 g of the title compound as a solid, mp 228-230° C.
