The title compound, C20H25NO3S2, was obtained by the reaction of (S)-2-methyl-N-[(S)-1-phenyl-3-(phenylthio)but-3-enyl]propane-2-sulfinamide with 3-chloroperoxybenzoic acid (mCPBA) in dichloromethane solution. The absolute configuration was assigned by reference to the unchanging chiral centre in the synthetic procedure. The dihedral angle between the two benzene rings is 73.3 (2)°. The molecular conformation is likely influenced in part by intramolecular C—H...O hydrogen bonds, while the crystal packing is stabilized by intermolecular N—H...O hydrogen bonds and C—H...π interactions.
