【 摘 要 】

In the title compound, C14H14ClNO4, the dihedral angle between the quinoline ring system (r.m.s. deviation = 0.0142 Å) and ester planes is 18.99 (3)°. The C—O—C—Cm (m = methyl) torsion angle is −172.08 (10)°, indicating a trans conformation. In the crystal, the molecules are linked by C—H...O and C—H...N interactions, generating layers lying parallel to (101). Aromatic π-π stacking [centroid–centroid distances = 3.557 (2) and 3.703 (2)Å] links the layers into a three-dimensional network.
