11 α,17 α,21-trihydroxypregnoster-4-ene-3 can be used, 20-diketone (I. e. epihydrocortisone) is acetylated by (21-hydroxyl), sulfonylated by (11-hydroxyl) and eliminated [forming 9(11)-double bond], (17 α-hydroxyl, 3-Keto) acetylation (3-ketyl and 4-double bonds are converted into 3-hydroxyl, 3-and 5-double bonds), (6 β-position) Fluorination and hydrolysis (3-position ketone group and 4-position double bond recovery), (6 β-fluorine) translocation, [9(11)-position double bond hypobromic acid] addition and epoxidation The product is prepared.
