phenothiazine antipsychotic drugs thioridazine, mesoridazine and sulforidazine were synthesized in six steps from commercially available 2-(2-hydroxyethyl)piperidine. The key step involved ruthenium tetroxide oxidation of N-protected 2-(2-chloroethyl)piperidine. The products were then oxidized to obtain the phenothiazine ring 5-sulfoxide analogues.
