该中间体在本合成路线中的序号：(XII)Dehydroepiandrosterone (VIII) was treated with o-phenylenephosphorochloridite (V) and then with iodine to afford iodide (IX), which was reduced to (X) by means of Zn and AcOH. Bromination of (X) with CuBr2 gave bromoketone (XI), and this was hydrolyzed to hydroxyketone (XII) upon treatment with aqueous NaOH in the presence of pyridine and oxygen. Subsequent treatment of (XII) with diethyl (2-chloro-1,1,2-trifluoroethyl)amine (XIII) afforded the target fluoroketone
