Abstract
In the title compound, C17H21NO2. the central pyridine ring is almost plana r and the outer rings are half-chairs. The O atoms of the keto groups devia te significantly from the mean plane passing through their corresponding ri ngs. The molecule contains a pseudo-mirror plane which passes through the c entral N and C atoms and the molecule is slightly folded along an axis pass ing through the same atoms. The dihedral angle between the outer rings is 6 .5(2)degrees. The packing is stabilized by an intermolecular C-H ... O hydr ogen bond.
