A solution of bromine (1.61 g) in acetic acid (4 ml) was added dropwise to a mixture of 5-acetyl-2-acetylaminomethylthiazole (2.00 g), 30 (W/W) % hydrobromic acid solution in acetic acid (5 ml) and acetic acid (40 ml) at ambient temperature. After stirring for 24 hours at ambient temperature, the resulting precipitate was collected by filtration and washed with acetic acid to give 2-(acetylaminomethyl)-5-bromoacetylthiazole (3.00 g).
