Versuchsvorschrift

A solution of 3-benzyloxy-7-chloro-1-cyclopropyl-6-fluoro-1H-quinazoline-2,4-dione (Example E-3, 0.162 g, 0.44 mmol) in DMF (3.0 mL) was reacted with pyrrolidin-3-yl-methyl-carbamic acid tert-butyl ester (0.40 g, 2.0 mmol) and triethylamine (0.63 mL, 4.5 mmol) then heated to 70° C. for 2 days. The mixture was then cooled, diluted with H2O, and extracted with ethyl acetate. The organic layers were combined, dried with sodium sulfate, and concentrated. The residue was then purified by column chromatography (silica gel, 1:1 hexanes/ethyl acetate) to provide 0.127 g of the title compound as a solid.
