The title compound, C21H18N4O2, crystallizes with one independent molecule in the asymmetric unit. The 6-methylquinoxaline-2,3(1H,4H)-dione unit is essentially planar. The dihedral angles between the mean plane of the 6-methylquinoxaline-2,3(1H,4H)-dione ring and its pendant pyridin-2-yl rings are 85.1 (3) and 73.8 (4)°. The pyridin-2-yl rings are inclined pointing away from the 6-methylquinoxaline-2,3(1H,4H)-dione ring system. In the crystal, molecules are linked by weak C—H...O interactions, forming a three-dimensional network structure.
