You can use 3 β-hydroxyprogesterone -5,16-diene -20-keto -3-acetate, (I. e. gestational dienolone acetate), through the (16-position double bond and methonitromethylurea) Addition and elimination to generate 3 β-hydroxy-16 β-methylprogesterone -5,16-diene -20-keto -3-acetate, then it is catalyzed by (16-position double bond) epoxidation, (epoxy group) ring opening (forming 17 α-hydroxyl and 15-position double bond), (15-position double bond) hydrogenation and hydrolysis (removal of 3-position acetyl group) to prepare the product.
