Procedure

2-Methoxypyrimidin-4(1H)-one (1.00 g, 7.93 mmol) and n-iodosuccinimide (3.57 g, 15.86 mmol) were mixed in DMF (8 mL) under a nitrogen atmosphere. The reaction mixture was stirred at 70° C. for 2.5 h. The reaction mixture was cooled to room temperature, diluted with water, and extracted with EtOAc (3×). The combined organic layers were washed with sat. sodium chloride, dried over magnesium sulfate, filtered, and concentrated. The resulting solid was suspended in DCM, filtered, and washed with DCM to give 5-iodo-2-methoxypyrimidin-4(1H)-one. [M+1]=252.9.
