Method for preparing azelnidipine crystals |
| abstract |
The present invention provides a method for preparing α-form crystals of azelnidipine. The preparation of α-form crystals of azelnidipine is obtained by dissolving β-form crystals of azelnidipine in an aprotic solvent to provide a solution of azelnidipine. Process, An aprotic and non-polar antisolvent is added to the solution to form an azelnidipine α-form precipitate and a method of recovering the precipitate. [Selection figure] None |
