The absolute configuration of the title compound (TKS159, C15H22ClN3O3) has been determined. The bent conformation of the molecule, in which the aromatic and pyrrolidine rings are at nearly 60° to each other, is maintained by intra- and intermolecular hydrogen bonds. A three-demensional network of hydrogen bonds is formed among the amino, hydroxy and carbonyl groups of neighbouring molecules.
