摘要
2-Chloro-N-phenylacetamide and N-(benzo[d]thiazol-2-y1)-2-chloroacetamide are doubly electrophilic building blocks for the formation of ring annulated thiazolo[3,2-a]pyrimidinone products. This synthetic route involves formation of the title compound in acceptable product yields by the elimination of the by-product, aniline/2-aminobenzothiazole. Analytical and spectral studies, as well as single crystal X-ray data on the representative compound 6c confirmed the structure of all the reaction products. (C) 2013 Elsevier Ltd.
