Abstract

The title compound, C15H21NO4S, crystallized with two independent mol­ecules in the asymmetric unit in which the dihedral angles between the mean planes of the benzene and cyclo­hexane rings are 78.3 (2) and 67.6 (2)°. The substituents of the cyclo­hexyl rings are in equatorial orientations. In the crystal, both mol­ecules form R22(6) carb­oxy­lic acid inversion dimers via pairs of O—H⋯O hydrogen bonds. Further N—H⋯O and C—H⋯O inter­actions generate a three-dimensional network.
