Reaction Conditions

Reaction Steps

To a solution of 3-acetylpyridine (5.00 g, 41.3 mmol) in acetic acid (100 ml) was added 47% hydrobromic acid (7.10 ml, 41.3 mmol), and a solution of bromine (2.12 ml, 41.3 mmol) in acetic acid (50 ml) was added dropwise under ice-cooling. After the completion of the dropwise addition, the reaction mixture was heated to 80° C. and the mixture was stirred for one hr. After cooling, the precipitated crystals were collected by filtration, washed with ethanol-ethyl acetate and dried under reduced pressure to give white crystals.
