Abstract: Novel heterocyclic derivatives of 3H-phenoxazin-3-one 6(a-d), [1,4]benzoxazino[2,3-b]phenoxazine 7(a-d) and imidazo[4,5-b]phenoxazin-2(1H)-one 9(a-d) are prepared by condensing 2,5-dibromo-3,6-dimethoxy-1,4-benzoquinone 4 with substituted ortho-aminophenols 5(a-d) and urea 8 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.

Keywords: 2 , 5-Dibromo-3 , 6-dimethoxy-1 , 4-benzoquinone , Ortho-aminophenol , Urea , 3H-Phenoxazin-3-one , Condensation , Spectral data.
