Reaction Steps

To a solution of 4-iodopyridin-2(1H)-one (3 g, 0.013 mol) and K2CO3 (3.55 g, 0.026 mol) in DMF (30 mL) was added iodomethane (4.7 g, 0.033 mmol). The mixture was stirred at room temperature overnight. Water and EtOAc were added. The organic phase was dried over Na2SO4 and concentrated to give 4-iodo-1-methylpyridin-2(1H)-one (1.6 g, 53%).
