Participants

Reaction Steps

To a solution of 2-methyl-phenothiazin-3-one (0.23 g) in 12 ml dichloroethane was added triethylamine (0.8 ml) and n-butanethiol (0.7 ml). The mixture was stirred at room temperature for 72 hours. 2,3-Dichloro-5,6-dicyano-1,4-benzoquinone (0.22 g) was added. The mixture was stirred at room temperature for 2 hours. The mixture was stirred at room temperature for 2 hours. The solvent was removed in vacuo and the residue was chromatographed on neutral alumina (Act III) eluting with 15% EtOAc/hexane to give the title compound (120 mg), m.p. 97° C.
