Scheme 8 provides a synthetic route to a 1-acetamido-N-ethyl phenazine derivative (35). A 3-amino-catechol hydrochloride (30) is reacted with silver oxide and anhydrous sodium sulfate in ethyl acetate to give 3-amino-1,2-quinone (31), which is further reacted in situ with ortho phenylenediamine (32) to give 1-amino phenazine (33). The amino phenazine (33) is acetylated with acetic anhydride in acetic acid to give 1-acetamido phenazine (34). The resulting 1-acetamido phenazine is reacted with diethyl sulfate in the presence of potassium carbonate to give N-ethyl-1-acetamido-phenazine (35).
