چکیده
The title compound, C(16)H(28)N(2)O(3)S, is dimerized by inversion symmetry-related inter-molecular O-H⋯N hydrogen bonding, forming an R(2) (2)(16) motif. The dimers are also linked through inter-molecular C-H⋯O hydrogen bonding. The compound is chiral with a stereogenic centre located in the thia-zole ring, but in the crystal structure it forms a racemate. The thia-zole ring has an envelope conformation, while the cyclo-hexane and morpholine rings adopt chair conformations.
