Abstract: In the title compound, C25H29BrN4O3S2, the benzene rings bridged by the sulfonamide group are tilted relative to each other by 63.9 (1)° and the dihedral angle between the sulfur-bridged pyrimidine and benzene rings is 64.9 (1)°. The molecular conformation is stabilized by a weak intramolecular [pi]-[pi] stacking interaction between the pyrimidine and the 2,4,6-trimethylbenzene rings [centroid-centroid distance = 3.766 (2) Å]. The piperidine ring adopts a chair conformation. In the crystal, molecules are linked into inversion dimers by pairs of N-H...O hydrogen bonds and these dimers are further linked by C-H...O hydrogen bonds into chains propagating along [010].
