Exploration of scope of an optimized one‐pot sequential procedure for preparing of 2,4‐di‐ and 2,4,5‐tri‐substituted thiazoles has been accomplished. The synthesis was performed by the initial formation of a β‐keto‐thioester intermediate from nucleophilic substitution of α‐bromoketones with thioacid potassium salts, followed by treatment with ammoniumacetate and one equivalent of acetic acid in toluene
