    • allo-Threonine derivative 3g was separated by filtration as its sodium salt. The sodium salts of 3g obtained from several runs were combined and extracted with ethyl acetate after acidification with 1 N HCl. A pure ligand could be recovered by concentration of the dried organic extracts and recrystallization from benzene.
