Abstract: The fused pyrazole and pyrimidine rings in the title compound, C16H15N3O2, are almost coplanar, being inclined to one another by 1.31 (12)°. The mean plane of this fused ring system is nearly coplanar with the phenyl ring, as indicated by the dihedral angle between their planes of 1.31 (12)°. The fused-ring system and the phenyl ring are nearly coplanar, as indicated by the dihedral angle of 1.27 (10)°. In the crystal, molecules form inversion dimers via pairs of C-H...O hydrogen bonds. C-H...N interactions connect the dimers into a three-dimensional network. In addition, [pi]-[pi] contacts are observed, with centroid-centroid distances of 3.426 (2) Å.
