tert-Butyl N-{3-[(3-chloro-1,4-dioxo-1,4-dihydro­naphthalen-2-yl)amino]­prop­yl}carbamate

In the title compound, C₁₈H₂₁ClN₂O₄, the mol­ecular sytructure is stabilized by two intra­molecular N—H...O hydrogen bonds. In the crystal, mol­ecules are linked by pairs of C—H...O hydrogen bonds, forming inversion dimers with graph-set motif R₂²(10). N—H...O hydrogen bonds further link the dimers into C(10) chains along [010].
