چکیده
The title compound, C(24)H(26)N(2)O(8), was synthesized by the cyclo-addition reaction of methyl 2-phenyl-acrylate, diethyl 2-amino-malonate and 4-nitro-benzaldehyde. The pyrrolidine ring exhibits an envelope conformation. The two benzene rings are located on opposite sides of the pyrrolidine ring and subtend a dihedral angle of 59.16 (14)°. The crystal packing is stabilized by N-H⋯O and weak C-H⋯O hydrogen bonding.
