Abstract
Heterocyclic derivatives of 3H-phenothiazin-3-one 6(a-d) are prepared by refluxing 2,5-dibromo-3,6-dimethoxy- 1,4-benzoquinone 4 with substituted ortho-aminothiophenols 5(a-d) in ethanolic solution of fused sodium acetate. The structures of newly synthesized compounds are characterized by using elemental analysis, IR, 1H NMR, 13C NMR and mass spectral data.
