Reaction Steps

The 2,3-dimethylbenzo(B)phenazine was prepared by the condensation of 2,3-diaminonapthalene with 4,5-dimethyl-1,2-benzoquinone in 4:1 ethanol to acetic acid at reflux for 2 hours. The phenazine was alkylated by the procedure of Synthesis Example 8, using iodomethane. Electrochemical analysis was consistent with an N,N'-dialkylated phenazine.
