(±)-N-(3-Hydr-oxy-1,2-diphenyl-prop-yl)-4-methyl-benzene-sulfonamide.

In the title compound, C(22)H(23)NO(3)S, the relative stereochemistry of the two stereogenic centres is anti with respect to the H atoms. The mol-ecular packing of the crystal shows a double-strand arrangement, consisting of one strand of (S*,S*) enanti-omers and one strand of (R*,R*) enanti-omers. Both strands lie parallel to each other along the a axis. Each strand is made up of dimers in which the mol-ecules are connected to each other via an inter-molecular O-H⋯O hydrogen bond between the hydroxyl groups and an O-H⋯π inter-action with the aromatic ring. These units are then connected to neighbouring dimers via N-H⋯O hydrogen bonds and C-H⋯O interactions. Intramolecular C-H⋯O interactions are also observed.
