Abstract

The title compound, C24H26N2O4, lies about a crystallographic twofold rotation axis. The cyclo­hexane rings adopts a chair conformation. The two pyridine rings form a dihedral angle of 41.02 (4)°. In the crystal, mol­ecules are linked via C—H⋯O and C—H⋯N hydrogen bonds into a layer parallel to the bc plane.
