Syntheses of six 8-substituted-2-carboxy-4-(4-fluorophenyl)-1,5-benzothiazepines having as the substituent fluoro, chloro, bromo, alkyl-methyl, alkoxyl-methoxyl and ethoxyl have been achieved by the reaction of 5-substituted-2-aminobenzenethiols with beta(-p-fluorobenzoyl)acrylic acid in ethanol saturated with hydrogen chloride gas. The products were tested for purity by TLC. Microestimation of nitrogen, IR and H-1 NMR & mass spectral studies have been used for the assignment of structures to the title compounds.
