چکیده
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.

In the title quinazolin-4-one derivative, C(23)H(18)N(2)O(3), both the benzoate [dihedral angle = 79.99 (6)°] and the 2-tolyl [89.02 (7)°] groups are close to orthogonal to the central fused ring system. Both aryl groups are orientated towards the quinazolin-4-one-bound methyl group. In the crystal, mol-ecules are connected into a three-dimensional architecture by C-H⋯O, C-H⋯N and C-H⋯π inter-a...
