実験手順
1α-Methyl-4-androstene-17β,19-diol dipropionate is dissolved in a 10% aqueous methanol solution and one equivalent of sodium bicarbonate is added. The solution is stirred and heated at its reflux temperature for one hour and poured onto ice water with vigorous stirring. The precipitate is removed by filtration, air dried and crystallized from hexane to yield 1α-methyl-4-androstene-17β,19-diol 17-propionate.
