Reaction Steps

To a solution of 2-fluoro-4-iodo-3-methylpyridine (1.68 g, 7.09 mmol) in 1,4-dioxane/water (1:1, 5.2 mL) was added concentrated HCl (5.5 mL). The resulting clear solution was heated to 100° C. After 1 h, the reaction mixture was allowed to cool to ambient temperature and was stirred overnight, during which time a precipate formed. The mixture was filtered and dried to a constant weight to afford 4-iodo-3-methylpyridin-2(1H)-one as a yellow solid 1.47 g.
