Abstract
A process for the preparation of 3-oxo-13-beta-ethyl-17-alpha-ethynyl-17-beta-hydroxy-4,9,11-triene, characterized in that it is subjected to 3-ethylenedioxy-17-oxo-13 beta-ethyl-4-gone, 9,11-triene to the action of an ethynylation agent, and then the acid hydrolysis of the alpha-ethynylated derivative 17 obtained as an intermediate is carried out.
