The asymmetric unit of the title compound, C(15)H(15)N(3)O(2)S, contains two independent mol-ecules corresponding to the R and S enanti-omers. The dihydro-pyrimidinone rings adopt a flattened boat conformation. One of the ethyl groups is disordered over two orientations with occupancy factors of 0.700 (7) and 0.300 (7). In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯O hydrogen-bonding inter-actions into one-dimensional chains along the c-axis direction. The chains are further connected by N-H⋯S hydrogen bonds, forming a three-dimensional network.
标题化合物C(15)H(15)N(3)O(2)S的不对称单元包含两个对应于R和S对映体的独立分子。二氢嘧啶酮环呈扁平船型构象。其中一个乙基在两个取向上无序，占有率分别为0.700 (7)和0.300 (7)。在晶体结构中，分子通过分子间N-H⋯O氢键相互作用沿c轴方向连接成一维链。这些链进一步通过N-H⋯S氢键连接，形成三维网络。
