The title compound, C20H22N4O7, is a glycoluril derivative with five fused rings. A benzene ring is fused to a seven-membered ring which includes two of the N atoms from separate rings of the glycoluril system, and the other two N atoms are linked to an O atom by two methylene groups. The structure is stabilized by intermolecular C-H...O hydrogen bonds.
