title: Methyl 11,14,16-triphenyl-8,12-dioxa-14,15-di-aza-tetra-cyclo-[8.7.0.0(2,7).0(13,17)]hepta-deca-2(7),3,5,13(17),15-penta-ene-10-carboxyl-ate.
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⋯π inter-actions are also observed.
