چکیده
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.
