چکیده
In the title compound C(37)H(32)Cl(2)N(2)O(4), the unsubstituted pyrrolidine ring shows a twist conformation whereas the substituted pyrrolidine ring shows an envelope conformation. The dimeth-oxy benzene ring is perpendicular to the tetra-lone ring, making a dihedral angle of 89.94 (5)°. Mol-ecules are linked into centrosymmetric dimers by N-H⋯O hydrogen bonds and the crystal structure is stabilized by C-H⋯π inter-actions and C-H⋯O hydrogen bonds. One meth-oxy group is disordered over two positions with the site occupancy factors of 0.84 (2) and 0.16 (2).
