摘要：

The title compound, C(18)H(20)N(2)O(2), 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-H center dot center dot center dot O hydrogen bonds link the molecules into dimers. These dimers are further connected via C-H center dot center dot center dot pi contacts.
