| titleOfInvention | Improved preparation method of mesylergosterol |
| abstract | The application relates to an improved preparation method of methanesulfonylergosterol, prepared by the following reaction, characterized in that, after the reaction is completed, water is added dropwise in three batches to the reaction solution, and the total amount of water added dropwise in three batches is 5% of the raw material compound ergosterol ~8 mass times, first drop the first batch of water until the reaction solution is clear, then drop the second batch of water until crystals are precipitated, then slowly stir for 0.5 to 2 hours, then add the third batch of remaining water dropwise. |
