In the title compound, C(19)H(12)N(2)O(3), the 1-benzofuro[3,2-d]pyrimidinone unit is approximately planar, the maximum deviation from the mean plane being 0.045 (1) Å. The attached phenyl ring makes a dihedral angle of 86.73 (6)° with the fused ring system. The packing of the mol-ecules in the crystal structure is mainly governed by C-H⋯π hydrogen-bonding inter-actions.
