NEW ROUTE for the SYNTHESES of SOME NOVEL DERIVATIVES of 3-ARYL BENZO[d] THIAZOLE-2(3H)-IMINE from HIGH SUBSTITUTED THIOUREAS

Abstract

We have developed herein a new approach to the diverse synthesis of novel derivatives of 3-aryl benzo[d]thiazole-2(3H)-imines (3a−g), by a two-component reaction between diazonium salt (2) and various synthesized N-acyl-N'-aryl thioureas (1a−g), in the presence of sodium tert-butoxide as strong base. Finally, it resulted in the production of the desired products with a moderate yield. The chemical structures of these synthesized compounds were confirmed by various physico-chemical methods viz. FT-IR, 1H-NMR, 13C-NMR, and elemental analysis.
