In the title structure, the 2,3-dihydro-1H-indole ring system is nearly planar, while the conformation of the 4H-pyran ring is close to a flattened boat. The mean planes of these fragments are approximately perpendicular to each other. In the crystal, the molecules are connected into layers by N—H⋯N and N—H⋯O hydrogen bonds.
