1-Tosyl-4-[2-(trifluoro­meth­yl)benz­yl]piperazine

In the crystal structure of the title compound, C₁₉H₂₁F₃N₂O₂S, the piperazine ring adopts a chair conformation. The dihedral angles between the mean plane of the piperazine ring and the tosyl and trifluoro­methyl­phenyl rings are 74.52 (3) and 68.30 (2)°, respectively. The sulfonamide N atom deviates from the plane defined by the three attached atoms by 0.327 (1) Å. The crystal structure is stabilized by weak C—H...π inter­actions.
