19-Methoxyandrost-4-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 acetone-hexane to yield 19-methoxyandrost-4-ene-3β,17β-diol diacetate.
