Abstract: In the title compound, C24H21ClN2O6, the two fused six-membered pyran rings adopt half-chair conformations. The dihedral angle between the pyrimidine ring and the chlorophenyl ring is 51.55 (3)°. In the crystal, molecules are linked by pairs of weak intermolecular C-HO hydrogen bonds, forming inversion dimers. A C-H interaction is also observed.
