Abstract
10-Acetyl-1-nitro-3-bromophenothiazine and 10-acetyl-2-bromo-4-nitrophenothiazine were synthesized by heating 2-acetamido-2′-nitro-4′,6′-dibromodiphenyl sulfide at 160–170°C in nitrobenzene in the presence of a copper catalyst. Saponification of these products led to 1-nitro-3-bromophenothiazine and 2-bromo-4-nitrophenothiazine.
