Acetic Anhydride → HCID 70506227, compound

Participants

Reaction Steps

6.5 g of 3β-benzoyloxy-15β,16β-methylene-5-androsten-17β-ol, 13 ml of acetic anhydride, and 26 ml of pyridine were heated for 1.5 hours to 95° C. After ice water precipitation, the sediment was filtered off and taken up in methylene chloride. The solution was washed with water, dried, and evaporated, thus obtaining 6.9 g of crude 17β-acetoxy-3β-benzoyloxy-15β,16β-methylene-5-androstene, used without further purification in the next stage.
