Procedure

Bromine (6.0 g) was added slowly to a solution of 5-acetyl-3-pyridinecarboxylic acid methyl ester (6.0 g) in dioxane (50 ml) at room temperature. The mixture was stirred at room temperature for 1 hour and then heated at 60°-70° C for 5 hours. The resulting precipitate was collected by filtration to afford 5-bromoacetyl-3-pyridinecarboxylic acid methyl ester hydrobromide (10.0 g).
