Reaction Steps
To a solution of 3-bromo-2-hydroxyquinoline (50 mg, 0.223 mmol) in DMF (1 mL) was added methyl iodide (0.017 mL, 0.268 mmol) and potassium carbonate (46.3 mg, 0.335 mmol.) at room temperature. The reaction mixture was stirred for 16 hours at room temperature. Water was added and the solution was extracted with ethyl acetate. The organic layer was washed with water then aqueous saturated sodium chloride solution. The organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo. The resulting residue was purified by silica gel column chromatography (developing solvent: hexane/ethyl acetate=/1) to give 3-bromo-1-methylquinolin-2(1H)-one (52 mg, MS: 238.1 [M+H+].)
