Unlike most of other aromatic amines, 4‐methoxyaniline with methyl comenate ( 1 ) in the mixture of acetic acid and methanol (1:1) gave two unexpected products with azomethyne moiety. The structures of new compounds were determined from their characteristic spectroscopic behaviour and were confirmed by X‐ray crystallographic measurements.
