Abstract

Process for the preparation of certain pregnadiene compounds, which comprises the reaction of a l6-beta acylate-methyl-1,4-pregnadiene-beta, 17 α, 21-triol-3,20-dione with a dehydrating agent, to obtain the corresponding 21-acylate of l6 β -methyl-l, 4.9 (11) -pregnatrien-17 α, 21-diol-3,20-dione.
