In this work new different hetero cyclic derivatives were synthesized that which including β-Lactam, teterazole and also thiazole rings.The starting material is 2-amino-6-methoxy-Benzothiazole. All these reactions follow by (TLC) and Measurement melting points for some of these derivatives. The compounds identified by FT-IR and some of them by 1H-NMR and 13C-NMR spectra., The prepared benzothiazole derivatives in this study gave good results through appearance of new bands and disapearance of other bands in formatted compounds that gave first data to formation benzothiazole derivative , while second technique represented by resonance spectra that gave also good results for formatted benzothiazole derivative.m in addition to flowing of all reactions by paper chromatography.
