| titleOfInvention |
Process for the preparation of cortexolone 17 a-propionate and new hydrated crystalline form thereof |
| abstract |
The present invention is directed to a process for the preparation of cortexolone 17α-propionate, comprising a hydrolysis reaction of an ortho-ester of formula (III)n nin which R is a hydrogen atom or a methyl group, nin the presence of a dilute solution of acetic acid. n The present invention is also directed to a hydrated crystalline form of cortexolone 17a-propionate obtained by such process. |
