Synthesis of monoazaphenoxazine viz., 3-chloro-1-azaphenoxazine (7) and some of its functionalized anilino derivatives (7a-e) via Buchwald-Hartwig amination methodology is reported. The intermediate 3-chloro-1-azaphenoxazine (7), was obtained by base-catalyzed condensation reaction between 2-aminophenol (8) and 2,3,5-trichloropyridine (9). Further reaction of compound 7 with various substituted anilines (10) via Tandem catalysis gave the anilino derivatives (7a-e). Structures of the synthesized compounds were assigned by spectroscopic methods.
