Disclosed is a process for the preparation of abiraterone and abiraterone acetate with high yields and purity. A key element of the method is the isolation of a crystalline intermediate that makes the process particularly suitable for implementation on an industrial scale. There is also provided a process for the production of abiraterone acetate by acetylation of abiraterone in the absence of bases or acetylation catalysts.
