| titleOfInvention | Preparation method of carboprost |
| abstract | The invention relates to a preparation method of carboprost, in particular to carboprost esterification obtained by adding a crystallization solvent into a crude carboprost product after completely reacting with hydroxyl-containing imine compounds in a polar aprotic solvent, stirring and crystallizing, and hydrolyzing. According to the technical scheme, the carboprost is prepared with high yield and high purity by combining the carboprost crude product with NHS (NHS) and then crystallizing and hydrolyzing, so that the method has the advantages of simplicity and convenience in operation and environmental friendliness, and the problem of low yield in the conventional method for preparing carboprost is solved. |
