| titleOfInvention | Optical Resolution Method of Amlodipine |
| abstract | The present invention relates to a method for optical resolution of amlodipines by using isopropanol solvent and optically active O,O′-dibenzoyl tartaric acid as chiral reagent. More particularly, the present invention relates to a method comprising (a) obtaining (R)— or (S)-amlodipine dibenzoyl tartrate salt or solvate thereof by reacting (R,S)-amlodipines with optically active O,O′-dibenzoyl tartaric acid in isopropanol solvent, and (b) treating the (R)— or (S)-amlodipine salt with a base, thus obtaining optically active amlodipine. |
