| titleOfInvention | Method for preparing abiraterone acetate |
| abstract | The invention discloses a convenient, rapid and economical method for massively preparing abiraterone acetate. According to the method, dehydroepiandrosterone acetate is used as a starting material, a keto carbonyl group is converted to hydrazone, and the abiraterone acetate is directly synthesized through iodination and Suzuki coupling reaction. According to the method, the operation is simple and convenient, the total yield of the three-step reaction is 34.7%, the product purity is 98.5%, the column chromatography separation purification is not required in the postprocessing, and the method is suitable for industrial production. |
