Abstract

A process for the preparation of esters of 11 β -hydroxy-l7- β -alkoxyloxy bottom of the pregnane series characterized in that it comprises treating an ester of 11 beta -trihaloacetoxy-17 β -alkyloxy lower of the pregnane series in a lower alkanol with a salt of an acid having a pKa which falls within the range of from about 2.3 to about 7.3 whereby the 11 β -trihaloacetyl group selectively solves to become a free hydroxy group.
