The title compound, C21H21N3O2, adopts a J-shaped conformation which appears to be at least partially directed by a weak intramolecular C—HN hydrogen bond. In the crystal, molecules are linked by N—HO hydrogen bonds into R22(8) and R22(14) cyclic dimers, which form a chain running parallel to the b axis.
