Procedure

To a mixture of 1-(3-fluorobenzyl)-4-hydroxypyridin-2(1H)-one (1.1 g, 5 mmol) in acetonitrile (15 mL) was added N-iodosuccinimide (1.1 g, 5.5 mmol) along with a ca. amount of dichloroacetic acid (0.1 mL). The reaction mixture stirred at room temperature for 1 hour under nitrogen. The mixture was chilled in an ice bath and filtered cold with fresh MeCl2. The beige solid was dried to afford the desired iodinated intermediate (1.21 g, 69%). ES-LRMS m/z 346.
