Abstract: The conformation adopted by the title compound, C20H21N3O3, in the crystal is `J'-shaped and 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, forming dimers with R22(8) motifs. Furthermore, these dimers connect to each other via C-HO and N-HO hydrogen bonds to form a three-dimensional network.
