title: 6'-Methyl-1',2',3',4'-tetra-hydro-spiro-cyclo-hexane-2'-quinazolin-4'-one.
abstract: The title compound, C(14)H(18)N(2)O, was synthesized by the reaction of cyclo-hexa-none and 2-amino-5-methyl-benzonitrile. In the mol-ecule, the cyclo-hexane ring displays a chair conformation, whereas the 1,3-diaza-cyclo-hexane 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-diaza-cyclo-hexane ring [planar within 0.052 (2) Å]. Mol-ecules are linked into centrosymmetric dimers via N-H⋯O hydrogen bonds.
