Abstract

Abstract The 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 ...
