| titleOfInvention | A kind of preparation method of metoprolol salt |
| abstract | The invention relates to a method for preparing metoprolol salt with simple operation, high yield, high quality, low cost and environmental friendliness. The method of the invention selects the acetone/water mixed solvent system, and adopts the back-dropping method to obtain the metoprolol salt. The method of adding dropwise into the organic acid solution is conducive to the full dissolution of the organic acid and the full progress of the reaction, which greatly shortens the reaction time and improves the conversion rate and yield of the reaction. The operation process is simplified, time and cost are saved, and the quality of the product is greatly improved. |
