In the title compound, C37H30N4O·C4H8O2, the dihedral angle between the pyrazole and dihydro­pyrazole rings is 74.09 (10)°. In the crystal, the components are linked into centrosymmetric tetra­mers (two main mol­ecules and two solvent mol­ecules) by C—H⋯O hydrogen bonds. C—H⋯π and π–π [shortest centroid-centroid separation = 3.6546 (9) Å] inter­actions are also observed.
