In the title compound, C(18)H(15)N(3)O(3)·0.5CH(2)Cl(2), 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 mol-ecules in the crystal structure is governed mainly by inter-molecular O-H⋯O and N-H⋯O hydrogen-bonding inter-actions and inter-molecular π-π inter-actions between benzofuro[3,2-d]pyrimidine units [the interplana ...[more]
