Sodium Iodide → 3-bromo-N-methylquinolin-8-amine

Participants

Reaction Conditions

Reaction Steps

A DMF (2 ml) solution containing 3-bromoquinolin-8-amine (223 mg), dimethyl sulfate (189 mg), potassium carbonate (415 mg), and sodium iodide (20 mg) were added to a tube and the tube was sealed, followed by stirring at 95° C. for 17 hours. The reaction solution was cooled to room temperature, ethyl acetate was added, an insoluble precipitate was removed, and the organic layer was washed with 1M hydrochloric acid, water, and saturated saline. Subsequently, the organic layer was dried over anhydrous sodium sulfate, the solvent was distilled away under reduced pressure, the obtained residue was purified by silica gel chromatography (n-hexane:ethyl acetate=0:1 to 1:1), and a yellow solid of 3-bromo-N-methylquinolin-8-amine (52 mg) was thus obtained.
