Abstract: The title compound, C₁₈H₂₀N₂O₂, was prepared by Mannich-type reaction of phenol, ethane-1,2-diamine and formaldehyde. The heterocyclic rings adopt half-chair conformations. The acyclic methylene groups attached to the N atoms are in an axial position. In the crystal, weak C-HO hydrogen bonds link the molecules into dimers. These dimers are further connected via C-H [pi] contacts.
