The title compound, C14H18N4O8, is a glycoluril derivative, composed of two five-membered rings in envelope conformations and two six-membered rings in chair conformations. In the crystal structure, inter-molecular C - H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. One methyl group and the H atoms on the adjacent C atom are disordered over two positions; the site-occupancy factors are ca 0.62 and 0.38...
