Abstract: The title compound, C₁₃H₁₁NO₃, adopts the keto-amine tautomeric form, with the H atom located on N rather than on O. This H atom is involved in a strong intramolecular hydrogen bond. There are two independent molecules in the asymmetric unit. The molecules are linked by intramolecular N-HO and O-HO and intermolecular O-HO hydrogen bonds into a three-dimensional network.
