Participants

Reaction Steps

To a suspension of 2-amino-4-methyl-5-acetylthiazole (15.6 g) in 30% solution of hydrogen bromide in acetic acid (120 ml) was added pyridinium hydrobromide perbromide (36 g) at ambient temperature and the mixture was stirred at the same temperature for 5 hours. The precipitate was collected by filtration, washed with diisopropyl ether, and dried over calcium chloride to give 2-amino-4-methyl-5-(2-bromoacetyl)thiazole hydrobromide (26.8 g).
