In the title compound, C18H15N3O3·0.5CH2Cl2, the fused ring benzofuro[2,3-d]pyrimidine system is essentially planar [maximum deviation 0.029 (1) Å]. The planes of the pyrimidinone and phenyl rings are nearly perpendicular [dihedral angle = 87.50 (14)°]. The packing of the molecules in the crystal structure is governed mainly by intermolecular O—H...O and N—H...O hydrogen-bonding interactions and intermolecular π–π interactions between benzofuro[3,2-d]pyrimidine units [the interplanar distances areca3.4 and 3.5 Å, and the distances between adjacent ring centroids are in the range 3.64 (1)–3.76 (1) Å]. The dichloromethane solvent molecule lies on a special position.

Out Of Plane

In the title compound, C18H18O6, the benzene rings are coplanar due to the centrosymmetric nature of the molecule, with an inversion centre located at the midpoint of the C—C bond between the two rings. Consequently, the methyl carboxylate substituents are oriented in atransfashion with regards to the bond between the benzene rings. The methyl carboxylate and methoxy substituents are rotated slightly out of plane relative to their parent benzene rings, with dihedral and torsion angles of 18.52 (8) and −5.22 (15)°, respectively. The shortest O...H contact between neighbouring molecules is about 2.5 Å. Although some structure-directing contributions from C—H...O hydrogen-bonding interactions are possible, the crystal packing seems primarily directed by weak van der Waals forces.
