In the title compound, C17H18N4O3·C3H7NO, the main disubstituted urea and solvate molecules are linked by pairs of N-HO hydrogen bonds. In the main molecules, the benzene rings form a dihedral angle of 15.59 (13)° a;nd two intramolecular O-HN hydrogen bonds influence the molecular conformation. In the crystal structure, weak intermolecular C-HO interactions link the hydrogen-bonded pairs into chains along the b axis. The chains associate via C-H interactions.
