Abstract: In the title compound, C21H23NO3S, both the thiazole and oxazolidine rings adopt twist conformations. The mean plane of the thiazole ring makes a dihedral angle of 61.02 (7)° with the oxazolidine ring mean plane, and dihedral angles of 22.72 (6) and 75.07 (6)° with the benzene rings. The benzene rings are almost perpendicular to one another, making a dihedral angle of 89.14 (6)°. There are bifurcated intramolecular C-H...O hydrogen bonds in the molecular structure. In the crystal, molecules are linked via C-H...[pi] interactions, forming chains propagating along [100].
