TECHNICAL PROCESS FOR THE PREPARATION OF PURE NIFEDIPINE FROM THE RAW PRODUCT INVOLVED IN SYNTHESIS |
| abstract |
Pure nifedipine can be readily prepared from a large scale by recrystallizing the crude nifedipine obtained in the synthesis with solutions of organic, solid at room temperature acids in an inert organic solvent in which these organic solid acids are soluble at room temperature. |
