Chelerythrine-type oxobenzo[c]phenanthridine bases were effectively synthesized by the action of 1,3-dimethoxybenzene on 2-(2-methoxycarbonylphenyl)-1-(N-methylformamido)naphthalenes in the presence of phosphorus oxychloride. The N-deformylation based on the Vilsmeier-Haack reaction is also discussed.
