In the title compound, C(18)H(16)N(4)O(2), the plane defined by the ethyl C atoms and the attached N atom is inclined to the adjacent pyridine ring at an angle of 67.87 (16)°. The dihedral angle between the two heterocyclic rings is 3.33 (16)°. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond and the crystal structure by inter-molecular C-H⋯O hydrogen bonds, forming a one-dimensional structure.
在标题化合物C(18)H(16)N(4)O(2)中，由乙基C原子和相连的N原子所定义的平面与相邻的吡啶环呈67.87 (16)°的夹角。两个杂环之间的二面角为3.33 (16)°。分子构象通过分子内N-H⋯O氢键得以稳定，晶体结构则通过分子间C-H⋯O氢键形成一维结构。
