In the title compound, C(15)H(8)Cl(4)N(2)O, the quinoxaline ring system is almost planar, with a dihedral angle between the benzene and pyrazine rings of 3.1 (2)°. The 2,4-dichloro-phenyl ring is approximately perpendicular to the pyrazine ring, with a dihedral angle of 86.47 (13)° between them. The crystal packing features inter-molecular N-H⋯O hydrogen bonds and π-π stacking inter-actions, with centroid-centroid distances in the range 3.699 (3)-4.054 (3) Å.
在标题化合物C(15)H(8)Cl(4)N(2)O中，喹喔啉环系几乎呈平面状，苯环和吡嗪环之间的二面角为3.1 (2)°。2,4-二氯苯基环与吡嗪环近似垂直，它们之间的二面角为86.47 (13)°。晶体堆积具有分子间N-H⋯O氢键和π-π堆积相互作用，质心间距在3.699 (3)-4.054 (3) Å范围内。
