(1R,3S)-1,1′-(1,3-Dihydro-2-benzofuran-1,3-diyl)bis(1,3-dimethylurea)

In the molecule of the title compound, C14H20N4O3, the five-membered ring adopts an envelope conformation with the O atom displaced by 0.207 (3) angstrom from the plane of the other ring atoms. Intramolecular C-H center dot center dot center dot O hydrogen bonds result in the formation of three five-membered rings having envelope conformations. In the crystal structure, intermolecular N-H center dot center dot center dot O hydrogen bonds link the molecules, forming R-2(2)(20) ring motifs, which produce two-dimensional polymeric sheets extending along the b axis. There are also two C-H center dot center dot center dot pi interactions. The H atoms of one of the methyl groups are disordered over two positions and were refined with occupancies of 0.50.
