Abstract 10-Methyl-2-chloro- and 2-chloro-3-methyl-3,4-diazaphenoxazines as well as 2-oxo-3,10-dimethyl-2,3-dihydro-3, 4-diazaphenoxazine were obtained by methylation of 2-chloro-3,4-diazaphenoxazines. Depending on the conditions, alkylation of 2-chloro-3,4-diazaphenoxazine with β-diethylaminoethyl chloride gave 1-ethylimidazolino[1′,2′∶1,2]pyridazo[3,4-b]-1,4-benzoxazine or 2-ethoxy-10-(β-diethylaminoethyl)-3,4-diazaphenoxazine. A number of 10-alkyl- and 10-dialkylaminoalkyl-2-chloro-3,4-diazaphenoxazines were obtained by condensation of 3,4,6-trichloropyridazine with substituted o-aminophenols.
