Deskripsi
In the title compound, C20H23N3O3, the dihydropyran ring adopts half-chair conformation. The chromene system makes a dihedral angle of 87.35 (5)° with the adjacent benzene ring. An intramolecular N—H...O hydrogen bond generates an S(6) motif, which stabilizes the molecular conformation. In the crystal, weak intermolecular C—H...O hydrogen bonds contribute to the stabilization of the packing.
