(S)-N-[1-(5-Benzyl­sulfan­yl-1,3,4-oxa­diazol-2-yl)-2-phenyl­eth­yl]-4-methyl­benzene­sulfonamide

The title compound, C(24)H(23)N(3)O(3)S(2), crystallizes with two independent mol­ecules in the asymmetric unit. They differ essentially in the orientation of the tolyl rings, between which there is π–π stacking (centroid–centroid distance = 3.01 Å). The absolute configuration was confirmed by the determination of the Flack parameter [x = 0.008 (9)]. In the crystal, mol­ecules are connected by two classical N—H⋯N hydrogen bonds and two weak but very short C—H⋯O(sulfon­yl) inter­actions, forming layers lying parallel to the bc plane.
