Abstract

We synthesized the five compounds of azo bridged ethoxybenzothiazole substituted phenyl ester derivatives by using
Dicyclo Hexyl Carbodiimide (DCC) and a catalytic amount of Dimethyl amino pyridine (DMAP) as a nucleophile. All
the compounds structures were confirmed by IR, NMR and mass spectrum. The synthesized compounds were screened for
antioxidant property by DPPH radical scavenging method. (E)-4-[(6-ethoxy benzothiazol-2-yl) diazenyl] phenyl 2-methyl
benzoate (B1) and (E)-4-[(6-ethoxy benzothiazol-2-yl) diazeny]) phenyl 4-fluoro benzoate (B5) showed comparable
activities.
