In the crystal structure of the title compound, C11H10N2O2, there are two independent mol-ecules, A and B, with different conformations. In mol-ecule A, the pyran ring adopts a half-chair conformation, and in molecule B, it adopts an envelope conformation. The structure is stabilized by N - H⋯O hydrogen-bonding inter-actions, resulting in chains of mol-ecules. Further stability is provided by offset π-π stacking inter-actions between the benzene rings in adjacent chains, with centroid-centroid distances of 3.860 (5) Å for the benzene rings ...
