The title compound, C(21)H(23)ClN(2)O(2), was synthesized from N-amino-α-terpinene maleimide and 2-chloro-benzaldehyde. There are two independent mol-ecules in the asymmetric unit which are linked via an inter-molecular C-H⋯O hydrogen bond. The crystal studied was found to be a partial merohedral twin, with a 0.74 (7):0.26 (7) domain ratio.
