Abstract: The molecule of the title compound, C₂₃H₂₃ClN₂O₄, 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 (M) = 35.3 (1)°. The packing is stabilized by C-H interactions and offset - stacking (centroid-to-centroid distance = 3.849 Å, interplanar distance = 3.293 Å and slippage = 1.994 Å) between phenyl rings, leading to a two-dimensional network.
