In the title compound, C(25)H(21)F(2)N(3)O(5), the pyrimidine and difluoro-benz-yloxy rings are twisted away from the central quinoline ring system, making dihedral angles of 54.6 (1) and 74.1 (1)°, respectively. A weak C-H⋯O inter-action links symmetry-related mol-ecules, forming a pseudo-dimer. π-π inter-actions between the quinoline rings of symmetry-related mol-ecules [centroid-centroid distance = 3.5479 (10) Å] link these dimers into chains parallel to [101]. Weak C-H⋯π inter-actions join adjacent chains, forming a two-dimensional layer parallel to (101).
在标题化合物C(25)H(21)F(2)N(3)O(5)中，嘧啶环和二氟苄氧基环与中心喹啉环系统发生扭曲，二面角分别为54.6 (1)°和74.1 (1)°。一个弱的C—H⋯O相互作用连接对称相关的分子，形成一个假二聚体。对称相关分子的喹啉环之间的π-π相互作用[质心-质心距离 = 3.5479 (10) Å]将这些二聚体连接成平行于[101]的链。弱的C—H⋯π相互作用连接相邻的链，形成一个平行于(101)的二维层。
