The 1‐substituted‐5 H ‐benzo[2,3‐ a ]phenothiazin‐5‐one, 4‐substituted‐5 H ‐benzo[6,5‐ a ]phenothiazin‐5‐one and 6‐substitutedbenzo[a][1,4] benzothiazino[3,2‐ c ]phenothiazine derivatives were prepared by the condensation of 5‐substituted‐2,3‐dichloro‐1,4‐naphthoquinones with 2‐aminothiophenol. Reduction, acetylation and dehalogenation of the resulting compounds were carried out and the structures of the products were inferred from comparison with the authentic compound.
