Phenazinols can be O-methylated in excellent yields with diazomethane in diethyl ether, for example under these conditions 1,3,4,6,7,8,9-heptafluorophenazin-2-ol (84) forms 1,3,4,6,7,8,9-heptafluoro-2-methoxyphenazine (85) (Scheme 49).[‌84‌,‌112‌,‌193‌,‌200‌] Similarly, phenazine-1,6-diol is dimethylated in 56% yield.[‌84‌]
