Data collection

R factor = 0.046; wR factor = 0.105; data-to-parameter ratio = 15.6. In the title compound, C24H27BrN4O4S2, the molecule is twisted at the sulfonyl S atom with a C—S(O2)—N(H)—C torsion angle of 62.6 (3). The benzene rings bridged by the sulfonamide group are tilted to each other by a dihedral angle of 60.6 (1). The dihedral angle between the sulfur-bridged pyrimidine and benzene rings is 62.7 (1). The morpholine ring adopts a chair conformation. The molecular conformation is stabilized by a weak intramolecular – stacking interaction between the pyrimidine and the 2,4,6-trimethylbenzene rings [centroid–centroid distance = 3.793 (2) Å]. In the crystal, molecules are linked by N—H O hydrogen bonds into a chain along the b axis. Related literature For related structures of sulfonamides, see: Rodrigues et al. (2011); Akkurt et al.
