Abstract
A process for preparing a hydrocortisone compound of formula: ** (See formula) ** wherein R1 is said hydrocortisone minus its hydroxyl group in position 21; L is selected from the group consisting of - (CH2) n-, -C6H4-, -O- (CH2) n- and -NH- (CH2) n, where n is a number from 1 to 6, each R representing a selected member from the group consisting of the groups hydrogen, alkyl, hydroxyalkyl, aminoalkyl, aryl and aralkyl containing up to ten carbon atoms in each group and Z- is a pharmacologically acceptable anion; which consists in reacting a hydrocortisone compound containing a hydroxyl group at position 21 with an amino compound and a compound capable of providing a pharmacologically acceptable anion.
