| titleOfInvention | PROCESS FOR PREPARING 17-ACETYL OXYPROGESTERONE |
| abstract | The invention relates to the preparation of 17-acetyloxyprogesterone. The title compound is an important source of steroid hormone drugs such as medroxyprogesterone or chlormadinone acetate, which are used in contraceptive and gestagen medicines. The process for the preparation of 17-acetyloxyprogesterone is characterized in that 17-hydroxyprogesterone by acylation with acetic anhydride under the action of a strong acid expediently with the addition of further solvents to a mixture of 17-acetyloxy-pregn-4-en-3,20- converted dion and * and without intermediate isolation by adding hydrolyzing substances or mixtures of substances in the title compound. {17-Acetyloxyprogesterone; 17-hydroxyprogesterone; acylation; acetic anhydride; Substances, hydrolyzing; Solvent; Steroid hormone drugs} |
