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—H
O interaction occurs. In the crystal, molecules are linked into inversion dimers through pairs of C—HN interactions. Weak C—Hπ interactions are also observed.

The title compound C28H22O2, basically consists of three ring systems, viz. a central benzene ring, with a lateral napthalene group to which it subtends a dihedral angle of 66.56 (4)° and a tetrahydropyran ring exhibiting a half-chair conformation. The molecular structure is stabilized by a weak intramolecular C—HO interaction, while the crystal packing features weak C—Hπ contacts.
