摘要：

The molecule of the title compound, C18H15NO3, adopts the keto-amine tautomeric form, with strong intramolecular N-H center dot center dot center dot O hydrogen bonds classified as resonance-assisted hydrogen bonds (RAHBs). In the crystal structure, the molecules are stabilized by C-H center dot center dot O, C-H center dot center dot center dot pi and pi-pi interactions, forming rings and chains.
