Abstract
Abstract The reactions of 5-substituted-2-aminobenzenethiols with δ-(4-chlorobenzoyl)- and δ3-(4-bromobenzoyl)acrylic acids have been carried out in methanol containing traces of glacial acetic acid to yield in a single step, 8-substituted-2-carboxy-4-(4-chlorophenyl and 4-bromophenyl)-2,3-dihydro-1,5-benzothiazepines, the substituents being CI, Br as halogen; CH3 as alkyl, and OCH3 and OC2H5 as alkoxyl. The structural assignments have been made by a study of microanalyses of the elements and IR, 1H NMR and mass spectral studies of the title compounds.
