title: N-(2-{[5-Bromo-2-(morpholin-4-yl)pyrimidin-4-yl]sulfan-yl}-4-meth-oxy-phen-yl)-4-chloro-benzene-sulfonamide.
abstract: In the title compound, C(21)H(20)BrClN(4)O(4)S(2), the benzene rings bridged by the sulfonamide group are tilted relative to each other by a dihedral angle of 70.2 (1)° and the dihedral angle between the sulfur-bridged pyrimidine and benzene rings is 69.5 (1)°. The mol-ecular conformation is stabilized by a weak intra-molecular π-π stacking inter-action between the pyrimidine and the 4-chloro-benzene rings [centroid-centroid distance = 3.978 (2) Å]. The morpholine ring adopts a chair conformation. In the crystal, mol-ecules are linked into inversion dimers by pairs of C-H⋯N hydrogen bonds and these dimers are further connected by N-H⋯O hydrogen bonds, forming a tape along the a axis.
