title: tert-Butyl 4-(4-chloro-anilino)-6-methyl-2-oxocyclo-hex-3-ene-carboxyl-ate.
abstract: In the title compound, C(18)H(22)ClNO(3), the dihedral angle between the benzene ring and the conjugated part of the enaminone ring is 55.19 (9)°. The ester substituent makes a dihedral angle of 81.0 (2)° with this latter moiety. The crystal structure features N-H⋯O and weak C-H⋯O inter-molecular inter-actions.
