The molecule of the title compound, C~26~H~30~N~2~O~4~S, adopts a folded conformation, with the sulfonyl-bound benzene ring lying over the pyridinone ring [centroid-to-centroid distance = 3.893β€…(1)β€…Γ…], forming a dihedral angle of 23.87β€…(5)Β°. The pyrrolidine ring adopts a twist conformation and the d
