| titleOfInvention | Method for purification of amlodipine free base |
| abstract | The invention relates to a method for the purification of the deprotected free base of amlodipine, present in the reaction mixture following deprotection of an N-protected amlodipine compound, whereby (i) the reaction mixture, containing the deprotected amlodipine free base, optionally after a preceding filtration, is evaporated to dryness, or the solvent removed from the reaction mixture, (ii) the amlodipine free base, contained in the residue thus obtained, is dissolved in a suitable solvent and (iii) the amlodipine free base is precipitated from said solution. |
