実験手順

A solution of 3β-ethoxy-17β-hydroxy-5-androsten-19-one acetate and sodium carbonate in 10% aqueous methanol is refluxed for a period of about four hours. The cooled solution is poured onto water. The crystals which form are filtered and recrystallized from an acetone-water mixture to yield 3β-ethoxy-17β-hydroxy-5-androsten-19-one.
