6′-Methyl-1′,2′,3′,4′-tetrahydrospirocyclohexane-2′-quinazolin-4′-one

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.
