In the title compound, C(23)H(25)BrN(4)O(3)S(2), the benzene rings bridged by the sulfonamide group are tilted relative to each other by 69.7 (1)° and the dihedral angle between the sulfur-bridged pyrimidine and benzene rings is 70.4 (1)°. The mol-ecular conformation is stabilized by a weak intra-molecular π-π stacking inter-action between the pyrimidine and the 4-methyl benzene rings [centroid-centroid distance = 3.633 (2) Å]. The piperidine ring adopts a chair conformation. In the crystal, mol-ecules are linked into inversion dimers by pairs of N-H⋯O hydrogen bonds.
在标题化合物C₂₃H₂₅BrN₄O₃S₂中,由磺酰胺基团桥连的苯环彼此倾斜69.7 (1)°,硫桥连的嘧啶环与苯环之间的二面角为70.4 (1)°。分子构象通过嘧啶环与4-甲基苯环之间的弱分子内π-π堆积相互作用得以稳定[质心-质心距离 = 3.633 (2) Å]。哌啶环呈椅式构象。在晶体中,分子通过N-H⋯O氢键对连接成反演二聚体。
