| 摘要 | Provided are acetaic abiraterone trifluoroacetate, a preparation method and an application of same. The acetaic abiraterone trifluoroacetate is obtained through a salt-forming reaction between acetaic Abiraterone and trifluoroacetic acid. The acetaic abiraterone trifluoroacetate undergoes self-purification through recrystallization, and dissociation and recrystallization are performed on the purified abiraterone acetate trifluoroacetate, so that the obtained acetaic abiraterone has a high purity, a high yield and stable quality, and is capable of meeting the requirement for mass production of acetaic abiraterone. | ||
