Quinazolinone (III) was prepared by treatment of aminobenzamide (I) with Gold's reagent (II) in refluxing dioxan. Subsequent chlorination using thionyl chloride gave chloroquinazoline (IV). Nucleophilic displacement of the chlorine atom of (IV) with 4-bromo-2-fluoroaniline (V) yielded the anilinoquinazoline (VI). The benzyl group of (VI) was then cleaved with trifluoroacetic acid, and the resulting hydroxyquinazoline (VII) was finally coupled with (hydroxyethyl)triazole (VIII) using DEAD and PPh3 to furnish the title compound.
