The mol-ecule of the title compound, C(23)H(23)ClN(2)O(4), contains a quinolyl unit linked to a functionalized pyrrolidine system with a 3,4-trans arrangement of the substituents. The unit cell contains two stereoisomers that have the absolute stereochemistry 3S,4R and 3R,4S. The pyrrolidine ring adopts a twist conformation with pseudo-rotation parameters P = 258.2 (3)° and τ(M) = 35.3 (1)°. The packing is stabilized by C-H⋯π inter-actions and offset π-π stacking (centroid-to-centroid distance = 3.849 Å, inter-planar distance = 3.293 Å and slippage = 1.994 Å) between phenyl rings, leading to a two-dimensional network.
