Abstract: In the title compound, C₂₂H₂₉NO₃, 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. The butyl substituent is nearly planar, this plane lying almost perpendicular to the least-squares plane of the heterocyclic ring. Intermolecular O-HO hydrogen bonds link the molecules into extended chains and the compound also exhibits some weak intermolecular C-HO interactions.
