In the title compound, C(24)H(21)ClN(2)O(6), the two fused six-membered pyran rings adopt half-chair conformations. The dihedral angle between the pyrimidine ring and the chloro-phenyl ring is 51.55 (3)°. In the crystal, mol-ecules are linked by pairs of weak inter-molecular C-H⋯O hydrogen bonds, forming inversion dimers. A C-H⋯π inter-action is also observed. ...[more]
