In the title molecule, C20H17Cl2NO2, the pyrrole moiety makes dihedral angles of 63.42 (11) and 70.43 (12)° with the chlorobenzene rings. The ethoxycarbonyl unit is present in a synperiplanar conformation with respect to the pyrrole ring, as indicated by the dihedral angle of 14.5 (3)°. In the crystal, molecules are linked into chains parallel to the a-axis direction by weak C-HO hydrogen bonds.
