Abstract
A method for the preparation of pregnene compounds constituted by esters of dexa- and betamethasone, of the general formula (I), ** (see formula) ** In which R1 is an unsaturated or saturated aliphatic hydrocarbon group having from 8 to 14 carbon atoms, R2 is an alpha-oriented or beta-oriented methyl group, and N is a positive integer from 3 to 7, which method comprises reacting a saturated fatty acid or a salt thereof, said fatty acid having the formula: ** (see formula) ** In which R1 and n are as defined above, with dexa-metasone or beta-methasone or an active 21-ester thereof, the metasone having the aforementioned having the formula: ** (see formula) ** In which R2 is as defined above.
