In the title compound, C21H19ClN2O2, the benzene ring and the naphthalene ring system are oriented at a dihedral angle of 65.24 (10)degrees. In the crystal, N-H center dot center dot center dot O, C-H center dot center dot center dot N and C-H center dot center dot center dot O hydrogen bonds link the molecules, forming chains along the b- axis direction. Further C-H center dot center dot center dot O hydrogen bonds link the chains, forming corrugated sheets lying parallel to (10 (1) over bar).
