Synthesis and Characterization of Some New Heterocyclic Compounds Derived from Benzothiazole

摘要

The present work involves study of some new 1,3-oxazepine and diazepines derivatives by cycloaddition reaction between Schiff s bases and (Succinic imide, phthalic imide, and 3-nitophthalic) anhydride with dry benzene as a solvent. Oxazepine and diazepines derivatives from 4-chloro-6-nitrobenzo[d]thiazol-2-amine were synthesized. These derivatives were synthesized by the reaction of Schiff base with different anhydrides in presence of dry benzene. The starting material was 4-Chloro-6-nitro 2- aminobenzothiazole which prepared from 2-Chloro -4-nitroaniline and ammonium thiocyanate with presence of bromine and sodium acetate. The prepared compounds have been characterized by melting points and some physical properties besides the FT-IR,H-NMR spectra. The purity for these compounds was checked by TLC.
