A process for preparing an enantiomeric form of 2-amino-3-(4-alkylaminophenyl)-propanoic acid of formula (I) or a salt thereof: ##STR1## in which Alk represents an alkyl radical containing 1 to 2 carbon atoms, from (L)-phenylalanine to obtain the (S)-enantiomer of 2-amino-3-(4-alkylaminophenyl)-propanoic acid, or from (D)-phenylalanine to obtain the (R)-enantiomer of 2-amino-3-(4-alkylaminophenyl)propanoic acid.
