2-Chloromethyl-quinazolin-4(3H)-one: To a solution of 2-amino-benzoic acid methyl ester (0.26 ml, 2 mmol) and chloro-acetonitrile (0.16 ml, 4.0 mmol) in dioxane (8 ml) at room temperature was added concentrated HCl (1.0 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 2 N NaOH aqueous to pH 7. The precipitation was collected by filtration, then washed with water and dried to give 309 mg (79.6%) of the title compound.
