摘要

In the title molecule, C(24)H(31)N(5)O(6), the two ethyl fragments are each disordered over two conformations [occupancy ratios 0.58 (13)/0.42 (13) and 0.56 (12)/0.44 (12)]. The crystal packing exhibits intermolecular non-classical C-H center dot center dot center dot O hydrogen bonds and pi-pi interactions between benzene rings [centroid-centroid distances = 3.836 (5) angstrom].
