In the title compound, C(24)H(30)N(6)O(5), the cyclo-hexyl ring adopts a chair conformation, while the remainder of the mol-ecule adopts a U-shape. The dihedral angles between the pyridine ring and the pendant pyrimidine rings are 69.04 (12) and 75.99 (9)°. The two pyrimidine rings, however, are nearly parallel to one another, with a dihedral angle of 8.56 (15)° between them. They are also involved in an intra-molecular π-π stacking inter-action with a distance of 3.6627 (18) Å between the ring centroids. In the crystal, C-H⋯O contacts link the mol-ecules into chains along the b axis.
在标题化合物C₂₄H₃₀N₆O₅中,环己基环呈椅式构象,而分子的其余部分呈U形。吡啶环与悬垂嘧啶环之间的二面角分别为69.04 (12)°和75.99 (9)°。然而,两个嘧啶环几乎相互平行,它们之间的二面角为8.56 (15)°。它们还参与了分子内的π-π堆积相互作用,环心之间的距离为3.6627 (18) Å。在晶体中,C—H⋯O接触将分子沿b轴连接成链。
