Benzimidazole-2-thione (2a) was converted to a new derivative of [1,3] benzimidazo[2,1-c] [2,4]benzothiazepin-12(7H)-one (3a) but naphtho[2,3- d]imidazol-2-thione (2b) and perimidin-2-thione (2c) were each converted to a derivative of the novel heterocyclic ring systems, naphtha [2',3':4,5] imidazo[2,1-c][2,4]benzothiazepin-15 (5H) -one (3b) and [2,4] benzothia zepino[4,3-a] perimidin-14(9H)-one (3c).
