1) The main product of m.p. 204°, which was previously obtained by the nitration of phenazine N-oxide, was converted into 3-methoxyphenazine 5-oxide by refluxing with methanolic solution of potassium hydroxide. 2) 1-and 2-Chlorophenazine were not nitrated with conc. sulfuric acid and potassium nitrate, even when the temperature was raised to 80°. 3) 1-, 2-, and 3-Chlorophenazine 5-oxides were substituted at the same 7-position by the nitro group.
