Preparation of methyl (S)-3-amino-3-(3′-pyridyl)propionate dihydrochloride in high enantiomeric purity by selective crystallization of a diastereomeric salt of a carboxylic acid precursor (W-BOC-protected) with (1R,2S)-(-)-ephedrine is described. Further demonstration of the usefulness of this procedure to resolve other 3-amino-3-[(substituted)pyridyl]propionic acids is also described.
