Reaction Steps

150 mg (1.11 mmol) of 1-(2-methylpyrid-3-yl)ethanone are dissolved in 10 mL of glacial acetic acid. 365 μl (2.22 mmol) of hydrobromic acid and 63 μl (1.22 mmol) of bromine are added to the medium. The reaction mixture is placed under magnetic stirring at room temperature for 1 hour. Ethyl ether is added to the solution until a precipitate appears. The precipitate corresponding to 2-bromo-1-(2-methylpyrid-3-yl)ethanone hydrobromide is filtered off, washed with ethyl ether and dried. The 280 mg of product obtained have the following characteristics:
