Process for the preparation of (S)-(+)-pregabalin (1) that racemic pregabalin (2) was solved in water, reacted with a chiral a-hydroxy-carboxylic acid or a mixture of chiral a-hydroxy-carboxylic acids in desired case in the presence of an achiral acid, (S)-(+)-pregabalin (1) was deliberated from the obtained diastereomer salt and in desired case the residue of racemic pregabalin (2) was regenerated. |
