In the title compound, C24H29Br2N5O6, a glycoluril derivative, the 1,4-dibromobenzene ring is fused to the seven-membered ring of the glycoluril unit containing two N atoms. The two five-membered rings in the glycoluril unit are approximately planar and the dihedral angle between them is 69.8 (2)degrees. The six-membered ring containing three N atoms adopts a chair conformation. The crystal packing is stabilized by an intermolecular non-classical C-H center dot center dot center dot O hydrogen bond and a weak C-H center dot center dot center dot pi interaction. Both of the ester groups are found to be disordered over two positions. The occupancies of the disordered positions were refined to 0.73(1):0.27(1) and 0.56(1):0.44(1).
