Reaction Steps

To a solution of 1-(2,4,6-trimethylpyridin-3-yl)ethanone (5.0 g, 30.6 mmol) in 33% HBr in acetic acid solution (10.2 mL) was added bromine (1.57 ml, 30.6 mmol) in acetic acid (10.2 mL) dropwisely. The reaction was stirred at 70° C. for 2.0 h. The solution was cooled to room temperature and washed with ether. The residue was dried under reduced pressure to give 2-bromo-1-(2,4,6-trimethylpyridin-3-yl)ethanone hydrobromide, which was used directly for the next step without further purification.
