Abstract
N-(1-hydroxy propyl) indole was prepared by the reaction of indole with trimethylenechlorohydrin in presence of powdered potassium hydroxide in the solvent medium of DMF stirring at first at room temperature for 4h and then at 400 c for 12h. N-(propyl acetate) indole was prepared by the reaction of N-(1-dydroxy propyl) indole with acetic anhydride and pyridine in the water bath for 2h. N-(propylacetate)-3- formylindole was synthesized by the reaction of N-(propyl acetate) indole with POCl3 and DMF mixture stirring at first at 00 c for 1h and then at 1000 c for 2h. 2-[N-(propylacetate) indolyl]-6- nitro benzothiazole was synthesized by the treatment of N-(propylacetate) -3- formylindole with 2-amino-5-nitro thiophenol in presence of Baker’s yeast in the solvent medum of DCM at room temperature for 30h. 2-[N-(1-hydroxy propyl) indolyl]-6-nitro benzothiazole was prepared by the reduction of 2-[N-(propylacetate) indolyl]-6-nitro benzothiazole with potassium hydroxide and ethanol. The monomer namely 2-[N-propyl acrylate) indolyl]-6-nitro benzothiazole was synthesized by the reaction of 2-[N-(1-hydroxy propyl) indolyl] – 6- nitro benzothiazole with acryloyl chloride in the medium of mixed solvent DCM and DMF and heated at reflux for 6h. Lastly the monomer was co-polymerzed with MMA in the solvent medium of NMP in a sealed ampule at 700 c for 50h.
