Abstract: The synthesis of 6-aryl derivatives of 8-methyl-11-azabenzo [a]phenothiazn-5-one is reported. This was achieved by reacting 2-amino-4-methylpyridine-3-thiol with 2, 3-dichloro-1-4-naphthoquinone under anhydrous basic condition to furnish the parent compound while 6-aryl derivatives were prepared by cross-coupling with arylboronic acids under nickel complex catalysis. The structures assigned to the synthesized compound were supported by spectroscopic and analytical data obtained.

Keywords: Synthesis, 2-amino-4-methylpyridine-3-thiol, 2, 3-dichloronapthoquinone, 8-methyl-11-azabenzoaphenothiazine-5-one
