The asymmetric unit of the title compound, C21H19N3O3S, contains two independent mol-ecules. In one mol-ecule, the 1,3-thia-zolidine ring forms dihedral angles of 86.19 (8) and 8.37 (8)° with the phenyl and benzene rings, respectively. The corresponding dihedral angles in the other mol-ecule are 69.60 (7) and 14.08 (7)°. The dihedral angle between the phenyl and benzene rings is 84.70 (8)° in one mol-ecule and 69.62 (8)° in the other. In the crystal, mol-ecules pack in layers approximately parallel to (10-2). There are weak C-H⋯O hydrogen bonds within these layers. Further weak C-H⋯O hydrogen bonding occurs between the layers to form a three-dimensional network. A weak C-H⋯π inter-action is also observed.
标题化合物C₂₁H₁₉N₃O₃S的不对称单元包含两个独立的分子。在一个分子中，1,3-噻唑烷环与苯环和苯基环分别形成86.19 (8)°和8.37 (8)°的二面角。另一个分子中的相应二面角分别为69.60 (7)°和14.08 (7)°。在一个分子中，苯环和苯基环之间的二面角为84.70 (8)°，在另一个分子中为69.62 (8)°。在晶体中，分子堆积成大致平行于(10 -2)的层。这些层内存在弱的C-H⋯O氢键。层与层之间还发生进一步的弱C-H⋯O氢键作用，形成三维网络。还观察到弱的C-H⋯π相互作用。
