Abstract
In the crystal structure of the title compound [systematic name: 6,7-dimethoxy-12-methyl-16,18-dioxa-12-azatetracyclo[12.7.0.04,9.015,19]henicosa-1(21),4,6,8,14,19-hexaen-3-ol], C21H25NO5, the benzene rings exhibits a dihedral angle of 14.95 (4)°. In the crystal, molecules are linked by pairs of O—H⋯O hydrogen bonding into inversion dimers. These dimers are further connected by C—H⋯O interactions.
