In the title compound, C16H18ClN3O, the cyclo-hexane ring adopts a distorted chair conformation. In the crystal, pairs of mol-ecules are linked by N-H⋯O hydrogen bonds into inversion dimers, forming R 2 (2)(10) ring motifs. These dimers are connected through C-H⋯N hydrogen bonds into chains along the a axis, forming layers parallel to (101).
