Reaction Steps
300 mg (2.22 mmol) of 1-(4-methylpyrid-3-yl)ethanone are dissolved in 20 mL of glacial acetic acid. 730 μl (4.44 mmol) of hydrobromic acid and 126 μl (2.44 mmol) of bromine are added to the medium. The reaction mixture is placed under magnetic stirring at room temperature for 2 hours. Ethyl ether is added to the solution until a precipitate appears. The precipitate corresponding to 2-bromo-1-(4-methylpyrid-3-yl)ethanone hydrobromide is filtered off, washed with ethyl ether and dried. The 550 mg of product obtained have the following characteristics:
