Ambiguous information obtained from H-1 NMR spectroscopy has prompted an investigation of the correct stereochemistry of the title compound, C34H39NO3Si, by X-ray diffraction analysis. An uncommon pseudoaxial-axial trans conformation was observed for the substituents Linked to the C-4 and C-3 atoms (IUPAC numbering). The pseudo-equatorial conformation of the methyl group joined to the C-l atom was also confirmed.
