  Article:   SYNTHESIS OF NEW BENZOTHIAZOLYL-PHENOTHIAZINE DERIVATIVES.

  Abstract:   A series containing 1-, 2-, 3- and 4-(benzothiazol-2yl)-10Hphenothiazine derivatives was advantageously prepared by the condensation of each corresponding phenothiazine-carbaldehyde regioisomer with 2-amino-benzenethiol. The reaction conditions were optimized and the structures of the new compounds were unambiguously assigned based on high resolution nuclear magnetic resonance spectroscopy and mass spectrometry. 

Key words: phenothiazine, benzothiazole, NMR
