6 BETA-Iodomethyl-19-norsitost-5(10)-en-3 beta-ol (V) was synthesized by homoallylic rearrangement of 19-iodositost-5-en-3 beta-ol (IV), which was obtained by the hydrolysis of 19-iodositost-5-en-3 beta-ol acetate (III) derived from the displacement of sitost-5-ene-3 beta, 19-diol 3-acetate 19-p-toluenesulfonate (I) with sodium iodide in isopropanol. The radioiodinated IV and V were prepared by isotope exchange with sodium iodide-I-131.
