Procedure
5-methyl phenazinium methosulfate was prepared by quaternizing 36.0 g (200 mmoles) of phenazine with 25.2 g (200 mmoles) of dimethyl sulfate in 300 ml of nitrobenzene in a 500 ml 3-neck, round-bottom flask. The mixture was gradually heated to 80 degrees Celsius and then held at that temperature for 2 hours. After cooling, the methosulfate salt was filtered off and washed with ethanol for a 53.8% yield.
