Process for preparation of abiraterone acetate |
| abstract |
The present invention relates to improvement in the process of preparation of abiraterone acetate or a pharmaceutically acceptable salt thereof wherein the improvement comprises purifying the crude 3-&-acetoxyandrosta-5,16-diene-17-yl trifluoromethane sulphonate by crystallization from a solvent to obtain acetoxyandrosta-5,16-diene-17-yl trifluoromethane sulphonate as a crystalline solid and converting it to abiraterone acetate or pharmaceutically acceptable salt thereof. |
