In the title compound, C33H26N2O4, the pyrazole ring makes dihedral angles of 15.13 (7) and 60.80 (7)° with the adjacent phenyl rings. Both dihydropyran rings exhibit half-chair conformations. A weak intramolecular C-HO interaction occurs. In the crystal, molecules are linked into inversion dimers through pairs of C-HN interactions. Weak C-H interactions are also observed.
