실험 절차

19-Methoxyandrost-5-ene-3β,17β-diol is dissolved in a mixture of acetic anhydride and pyridine and the solution allowed to stand overnight at room temperature. The solvents are removed under vacuum and the remaining residue crystallized from an acetone-hexane solution to yield 19-methoxyandrost-5-ene-3β,17β-diol diacetate.
