Abstract
In the title compound, C37H33BrN4O6, the pyrrolidine ring adopts an envelope conformation. The beta-lactam ring is planar and makes dihedral angles of 70.16 (13) and 28.32 (13)degrees with the phenyl and 4-methoxyphenyl rings, respectively. The molecular packing is stabilized by intramolecular C-H center dot center dot center dot O interactions and the crystal packing is determined by intermolecular N-H center dot center dot center dot O hydrogen bonds, and C-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions.
