8-Substituted-2,5-dihydro-2-(4-N-dimethylaminophenyl)-4-(4-methoxyphenyl)-1,5-benzothiazepines (5a-e) have been synthesized by reacting 5-substituted-2-aminobenzene-thiols (1a-e) with 4-Ndimethylaminobenzal-4-methoxy acetophenone (2) in dry ethanol saturated with hydrogen chloride gas. The products were tested for purity by tlc and characterized by elemental analysis for carbon, hydrogen and nitrogen and IR, 1H NMR and mass spectral studies.
Keywords: 1; 5-Benzothiazepine; hydrogen chloride gas 1; 5-Benzothiazepine; hydrogen chloride gas
