Reaction Steps

4-Acetylpyridine (10 g) was combined with 48% hydrogen bromide solution (18 ml) and heated to 70° C. Bromine (4.7 ml) dissolved in 48% hydrogen bromide solution (5 ml) was then added dropwise and heating then continued for 2.5 h. The precipitate which had formed was collected by filtration, washed with 1:1 methanol:hexane (20 ml) and dried to give a cream solid (19.5 g) as a 2:1 mixture of product:starting material by 1H nmr.
