3-Phenyl-2-(prop-2-ynyloxy)-1-benzofuro[3,2-d]pyrimidin-4(3H)-one

In the title compound, C19H12N2O3, 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 molecules in the crystal structure is mainly governed by C—H...π hydrogen-bonding interactions
