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

In the mol­ecule of the title compound, C(14)H(20)N(4)O(3), the five-membered ring adopts an envelope conformation with the O atom displaced by 0.207 (3) Å from the plane of the other ring atoms. Intra­molecular C—H⋯O hydrogen bonds result in the formation of three five-membered rings having envelope conformations. In the crystal structure, inter­molecular N—H⋯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⋯π inter­actions. The H atoms of one of the methyl groups are disordered over two positions and were refined with occupancies of 0.50.
