Reaktionsschritte
Following essentially the same procedure but substituting 19-hydroxhy-1β-methyl-4-androstene-3,17-dione and 19-hydroxy-6α-methyl-4-androstene-3,17-dione for the 19-hydroxy-4-androstene-3,17-dione above results in the preparation of 1β-methyl-19-triphenylsiloxy-4-androstene-3,17-dione and 6α-methyl-19-triphenylsilioxy-4-androstene-3,17-dione.
