AbstractThe cyclization of 2‐(2‐chloro(bromo)phenoxy)anilines and 3‐(phenoxy)pyridines to 10‐methylphenoxazines and 10‐methyl[1,4]benzoxazino[3,2‐b]pyridines, respectively, by means of dimethyl methylphosphonate is reported. The cyclization reaction proceeded with expulsion of methyl ether. Demethylation of some 10‐methylphenoxazines was achieved with pyridine hydrobromide. Nitration was carried out with sodium nitrite, and by reduction of the nitro groups the corresponding amines
