Participants

Reaction Steps

The 3,7-dibromophenothiazine (6.25 g, 17.5 mmol) was dissolved in 200 mL of chloroform (CHCl3). Sulfuryl chloride (SO2Cl2, 3.13 mL, 38.5 mmol) was added dropwise over 15 min. The dark mixture was stirred at RT for 36 h. The mixture was then filtered and the solid washed with CHCl3. The solid was collected and stirred in Et2O and the resulting green solid was filtered off and dried under vacuum to give a quantitative yield of the desired product.
