The title compound, C30H24N6O2·0.5CH3OH, a glycoluril derivative with two pyridine substituents on the convex face of the glycoluril system, is an important intermediate for the synthesis of more complex glycoluril derivatives. The compound crystallizes with two independent molecules in the asymmetric unit, one of which exhibits disorder of one benzene ring over two orientations with refined site occupancy factors 0.65 (4):0.35 (4). The crystal structure contains several short C—H...O contacts, and the methanol molecule forms an O—H...O hydrogen bond to one of the glycoluril molecules.
