Abstract: In the title compound, C₂₁H₂₅NO₃, a modified synthetic D-homo steroid, the cyclohexene ring adjacent to the aromatic ring adopts a half-chair conformation, while the cyclohexane ring has an ideal chair conformation. The heterocyclic ring adopts a 14-sofa conformation. In the crystal structure, intermolecular O-HO hydrogen bonds link the molecules into extended chains with graph-set motif C(12). The compound also exhibits some weak intermolecular C-HO interactions.
