Abstract: In the title compound, C₁₇H₂₂ClN₃O₂, the aromatic fused ring system and the amide group are close to being coplanar [dihedral angle = 14.66 (16)°]. Thus, the amide NH group is sterically blocked from forming a hydrogen bond by the pendant ethyl substituent of the adjacent five-membered ring. The NH group of the five-membered ring makes an intermolecular N-HO bond, resulting in centrosymmetric dimers of molecules containing R₂²(10) loops.
