3-benzodiazepin-4-yl)sulfanyl]ethanones were obtained by the alkylation of 1-aryl-2,3-benzodiazepine-4(3H,5H)-thiones with 1-aryl-2-bromoethanones. A reaction for the annulation of the thiophene core to the 1,2-diazepine ring as a result of intramolecular cyclization involving a 4-aroylmethylsulfanyl substituent and C(4)–C(5) bond of diazepine was developed.
