Ethyl 3,7-dichloroquinoline-8-carboxylate

Abstract

The title compound, C12H9Cl2NO2, was prepared by the esterification of 3,7-dichloro­quinoline-8-carboxylic acid with triethyl phosphite. The crystal structure is stabilized by aromatic π–π stacking between the benzene and the pyridine rings of neighbouring mol­ecules [centroid–centroid distances = 3.716 (2) and 3.642 (2) Å]. In addition, weak inter­molecular C—H⋯N hydrogen bonds are present in the structure.
