This article is from Acta Crystallographica Section E: Structure Reports Online, volume 70.AbstractIn the title compound, C20H18ClN3O3, the five- and six-membered heterocycles fused through a spiro C atom are inclined to each other at an angle of 87.4 1°. In the tricyclic ring system, the cyclo­hexene ring adopts an envelope conformation with the spiro atom as the flap. In the crystal, two sets of N—H⋯O hydrogen bonds link the mol­ecules into columns containing centrosymmetric R227 ring motifs and propagating along the b-axis direction.
