چکیده
In the title compound, C(22)H(26)N(2)O(2), the meth-oxy and the benzyl-idene groups are essentially coplanar, and the cyclo-hexane ring has a chair conformation. The two halves of the mol-ecule are related by a twofold rotation. The crystal structure is stabilized only by van der Waals inter-actions.
