In the title compound, C 18 H 20 O 5 , the hydroxyl and dimethoxyphenyl substituents are in axial positions. The heterocyclic ring is in a half-chair conformation. The molecules are linked by OÐHÁ Á ÁO hydrogen bonds, leading to the formation of a chain extended throughout the whole of the crystal.
