✦ Synopsis

In the title compound, C 23 H 31 NO 3 , a modified synthetic dhomo steroid derivative, 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. The structure displays some weak intermolecular C-HÁ Á ÁO interactions.
