Abstract: In the title compound, C29H25N5O3, the dihedral angle between the benzene ring and the pendant quinazoline ring system (r.m.s. deviation = 0.036Å) is 87.60 (17)°. The equivalent angle between the pyrazole ring and the phenyl group is 70.0 (2)°. The dihedral angle between the benzene and pyrazole rings is 30.7 (2)° and overall, the molecular conformation approximates to a Z shape. A short intramolecular C-H...O contact occurs. In the crystal, the molecules are linked by C[pi]-H...O-type hydrogen bonds and aromatic [pi]-[pi] stacking interactions [centroid-centroid distance = 3.860 (3) Å], generating a three-dimensional network.
