Reaction Steps

2-Amino-3-iodo-4-methylbenzoic acid (8.00 g, 29 mmol), formamide (11 mL, 289 mmol) and NMP (11 ml) were added to an 80 mL microwave vessel. The mixture was heated for 15 min at 210° C. The mixture was diluted with ice water and the precipitated solid collected by filtration. The solid was washed with water and dried to give 8-iodo-7-methylquinazolin-4(3H)-one (7.3 g, 88%) as a light brown solid. MS (M+H)+ 287.
