ABSTRACT: 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 di-hydro-pyran rings exhibit half-chair conformations. A weak intra-molecular C-H?O inter-action occurs. In the crystal, mol-ecules are linked into inversion dimers through pairs of C-H?N inter-actions. Weak C-H?? inter-actions are also observed.
