Abstract

In the title compound, C31H29ClN2O3, the two heterocyclic rings, belonging to a system of five condensed rings, adopt conformations intermediate between twist-boat and sofa. The secondary amide group is involved in a weak intramolecular N—H⋯N hydrogen bond. In the crystal, molecules are linked by pairs of C—H⋯Cl hydrogen bonds to form inversion dimers. These dimers are linked via a C—H⋯O interaction to form chains propagating along the b-axis direction.
