2-(2-Chloro­phen­yl)-3-(3,4-dimeth­oxy­phen­yl)quinoxaline

The title compound, C22H17ClN2O2, was synthesized by the condensation reaction between 1,2-phenyl­enediamine and 2-chloro-3′,4′-dimeth­oxy­benzil in boiling acetic acid. The chloro­phenyl and dimeth­oxy­phenyl rings make dihedral angles of 78.45 (5) and 35.60 (4)°, respectively, with the quinoxaline unit.
