Abstract

The title compound, C14H18N2O, was synthesized by the reaction of cyclo­hexa­none and 2-amino-5-methyl­benzonitrile. In the mol­ecule, the cyclo­hexane ring displays a chair conformation, whereas the 1,3-diaza­cyclo­hexane moiety of the bicyclic system has a sofa conformation with the spiro C atom displaced by 0.603 (2) Å from the rest of the atoms of the 1,3-diaza­cyclo­hexane ring [planar within 0.052 (2) Å]. Mol­ecules are linked into centrosymmetric dimers via N—H⋯O hydrogen bonds.
