Procedure

Further steps of the process are conducted as described in Example 1 hereinbefore. The solution of 9-methylphenazinium methylsulphate in distilled water is first irradiated for 3 hours and the reaction mixture is brought to the pH of 8.5 by using a 0.1N solution of sodium hydroxide, whereafter the irradiation is continued for additional 5 hours to give 0.79 g (58%) of 4-keto-9-methylphenazine in the form of blue crystals with the melting point of 133°-135° C.
