چکیده
In the title compound, C20H17N3O4, the central pyran ring adopts a boat conformation with the O atom and diagonally opposite C atoms displaced by 0.1171 (1) and 0.1791 (1) Å, respectively, from the mean plane defined by the other four atoms. The coplanar atoms of the pyran ring and the meth-oxy-benzene ring are nearly perpendicular, as evidenced by the dihedral angle 87.01 (1)°. The amine H atom forms an intra-molecular N-H⋯O(nitro) hydrogen bond. In the crystal, mol-ecules are linked into dimeric aggregates by N-H⋯O(nitro) hydrogen bonds, generating an R2(2)(12) graph-set motif.
