Versuchsvorschrift
A mixture of 21.9 g (112.5 mmol) of the product from Step 1 (11) and 38.9 g (168.8 mmol) of N-iodosuccinimide in 660 mL of acetonitrile was stirred at 80° C. under nitrogen for 16 hours. The reaction mixture was then allowed to cool to ambient temperature and the acetonitrile was removed in vacuo. The resulting solid was washed with water, saturated Na2O3S2, saturated NaHCO3, brine, and filtered. Drying under reduced pressure at 40° C. overnight yielded 29.8 g (92.9 mmol, 83%) of 2-(chloromethyl)-3-iodo-4H-pyrido[1,2-a]pyrimidin-4-one (12) as a light brown solid.
