In the title mol-ecule, C(13)H(16)N(2)O(2), the cyclo-hexyl-idene ring adopts a chair conformation. The intra-molecular N-H⋯O hydrogen bond influences the mol-ecular conformation: the benzene ring and the mean plane of the central C(O)NHN fragment form a dihedral angle of 4.9 (1) Å. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains propagated along [001].
