Reaction Steps

The 3-aminophenothiazin-5-ium triiodide was dissolved in DMF (40 mL) and Cs2CO3 was added followed by pyrrolidine (3 mL, 3 mmol). The resulting reaction mixture was stirred rapidly at room temperature for 48 h. The solvent was evaporated and the residue was dissolved in a 3:1 mixture of CHCl3/MeOH. The mixture was filtered and the solvent evaporated to give a residue, which was purified by flash silica gel chromatography to give a dark solid.
