Abstract: 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

interactions between benzofuro[3,2-d]pyrimidine units [the interplanar distances are ca 3.4 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.
