In the title compound, C(24)H(27)BrN(4)O(4)S(2), the mol-ecule is twisted at the sulfonyl S atom with a C-S(O(2))-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 mol-ecular conformation is stabilized by a weak intra-molecular π-π stacking inter-action between the pyrimidine and the 2,4,6-trimethyl-benzene rings [centroid-centroid distance = 3.793 (2) Å]. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into a chain along the b axis.
在标题化合物C₂₄H₂₇BrN₄O₄S₂中,分子在磺酰基S原子处发生扭曲,C-S(O₂)-N(H)-C扭转角为62.6 (3)°。由磺酰胺基团桥连的苯环彼此倾斜,二面角为60.6 (1)°。硫桥连的嘧啶环与苯环之间的二面角为62.7 (1)°。吗啉环呈椅式构象。分子构象通过嘧啶环与2,4,6-三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 = 3.793 (2) Å]。在晶体中,分子通过N-H⋯O氢键沿b轴连接成链。
