Procedure
A solution of 2-amino-5-iodobenzoic acid (14.2 g, 50 mmol) and formamidine acetate (6.75 g, 65 mmol) in ethanol (200 mL) was refluxed for 20 hours. After cooling to 0° C. the solid product was collected by filtration. Further drying in a vacuum provided 6-Iodo-4-quinazolinone (11 g, 81%) as a gray solid.
