Abstract
Though the synthesis of methylphenazine derivatives has been reported, the yield was generally very poor. A variation of the improved Wohl-Aue reaction, carried out in the presence of sodium amide, gave better yield. The syntheses of 1- and 2- methyl- and 1, 6-dimethylphenazines and their oxides, as well as that of 1-methoxy- 6-methyl- and 1-methoxy-8-methylphenazines are described.
