The complete mol-ecule of the title compound, C24H28N4O4, is generated by crystallographic inversion symmetry. The ethyl side chain is disordered over two sets of sites in a 0.57 (4):0.43 (4) ratio. The dihedral angles between the methyl-idene group and the phenyl ring and ester side chain (major conformation) are 7.61 (8) and 86.95 (8)°, respectively. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds, forming corrugated sheets lying parallel to (010).
标题化合物C24H28N4O4的完整分子由晶体学倒转对称性产生。乙基侧链在两组位置上无序排列，比例为0.57 (4):0.43 (4)。亚甲基与苯环和酯侧链（主要构象）之间的二面角分别为7.61 (8)°和86.95 (8)°。在晶体中，分子通过C—H⋯O氢键相连，形成平行于(010)的波纹片层。
