Methyl 6-(4-chloro-phen-yl)-2,4-dimethyl-1,3-dioxo-1,2,3,4,6,6a,7,12b-octa-hydro-chromeno[4',3':4,5]pyrano[2,3-d]pyrimidine-6a-carboxyl-ate.

ABSTRACT: 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.
