Notes:
The structure of the title compound, C18H18ClNO4, (I), comprises twisted molecules that associate by an intermolecular C—H...O close contact to one of the naphthoquinone O atoms. The other naphthoquinone O atom and the Cl atom are involved in intramolecular C—H close contacts, while no similar interactions are observed to the carbethoxy O atoms. The ethyl C atoms are disordered over two sites.
