✦ Synopsis
In the title compound, C~18~H~20~N~4~O~3~, a glycoluril derivative, the oxadiazinane six-membered ring displays a chair conformation and the bridgehead cyclohexane ring a boat conformation. In the crystal structure, intermolecular C—H...O hydrogen bonds may help to establish the packing.
