Abstract: In the title molecule, C16H14N4O, the indolizine ring system is essentially planar, with a maximum deviation of 0.013 (3) Å, and forms a dihedral angle of 7.52 (12)° with the pyrazole ring. In the crystal, weak C-HO hydrogen bonds and - stacking interactions, with a centroid-centroid distance of 3.6378 (16) Å, link molecules along .
