Reaktionsschritte

A solution of 2-amino-4-fluorobenzoic acid (3 g, 19.3 mmol) in formamide (30 ml) was heated at 150° C. for 6 hours. The reaction mixture was poured onto ice/water 1/1 (250 ml). The precipitated solid was collected by filtration, washed with water and dried to give 7-fluoro-3,4-dihydroquinazolin-4-one (2.6 g, 82%).
