Procedure

2-Fluoromethyl-quinazolin-4(3H)-one: To a solution of 2-amino-benzoic acid methyl ester (151 mg, 1 mmol) and fluoro-acetonitrile (0.14 ml, 2.5 mmol) in dioxane (5 ml) at room temperature was added concentrated HCl (0.05 ml) dropwise. The mixture was heated at 80° C. for 24 h and then cooled to room temperature. The resulting solid was collected and dissolved in water (10 ml), and the solution was neutralized with saturated aqueous NaHCO3 to pH 7. The solution was extracted by ethyl acetate. The extracts were evaporated, and the residue was purified by column chromatography on silica gel with ethyl acetate and hexane (1:1) as eluent, yielding 70 mg (39%) of the title compound.
