## Abstract An efficient synthesis of 3‐bromoacetyl‐4‐hydroxy‐6‐methyl‐2__H__‐pyran‐2‐one by bromination of dehydroacetic acid in glacial acetic acid is described. Novel 4‐hydroxy‐6‐methyl‐3‐(2‐substituted‐thiazol‐4‐yl)‐2__H__‐pyran‐2‐ones have been prepared from the reaction of 3‐bromoacetyl‐4‐hyd
