Single Process

A simple and efficient one-pot protocol has been developed for the synthesis of thiazole derivatives from readily available starting materials. Tribromoisocyanuric acid was successfully used for α-monohalogenation of β-keto esters in aqueous medium, which in the presence of thiourea and DABCO produced the corresponding 2-aminothiazoles in up to 87% yield. Extension of the reaction to thioacetamide and o-phenylenediamine led to 2-methylthiazole and quinoxalines, respectively. This approach enables telescoping of the two steps into a single process.
