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 co...

In the title compound, C21H21Cl2NO2, the piperidine ring adopts a distorted boat conformation. The phenyl rings substituted at the 2- and 6-positions of the piperidine ring subtend angles of 87.9 (7) and 70.8 (9)°, respectively, with the best plane through the piperidine ring. In the crystal, mol-ecules are connected by C-H⋯O and C-H⋯Cl inter-actions into layers in the ab plane.
