In the title compound, C(18)H(19)N(3)O(3), the tetra-hydro-pyrimidone ring adopts a distorted boat conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further linked via inter-molecular C-H⋯π inter-actions. In addition, an intra-molecular C-H⋯O hydrogen bond occurs.
在标题化合物C₁₈H₁₉N₃O₃中,四氢嘧啶酮环呈扭曲的船式构象。在晶体结构中,分子间的N-H⋯O氢键将分子连接成中心对称的二聚体,这些二聚体通过分子间的C-H⋯π相互作用进一步连接。此外,还存在分子内的C-H⋯O氢键。
