Phenothiazin‐5‐ium tetraiodide hydrate ( 2 ), the suggested oxidation product of phenothiazine with iodine, is treated with two equivalents of a dialkylamine to give 3‐(dialkylamino)phenothiazin‐5‐ium triiodides, 3‐6 . 3,7‐Disubstituted phenothiazin‐5‐ium iodides, 7‐9 , are obtained by the reaction of 3‐6 with an amine.
