چکیده
In the title compound, C(18)H(22)ClNO(5), the cyclo-hexene ring adopts a distorted half-chair conformation. The mol-ecular structure is stabilized by pairs of intra-molecular N-H⋯O and O-H⋯O inter-actions, generating S(6) motifs. In the crystal, the mol-ecules are linked by inter-molecular C-H⋯O inter-actions, forming centrosymmetric dimers.
