PROCEDURE

实验过程

17β,19-Dihydroxy-1α-methyl-4-androsten-3-one is dissolved in ethanol and sodium borohydride is added slowly under nitrogen. After stirring at room temperature for 4 hours, the solution is poured onto ice water containing a few drops of acetic acid. The solid which forms is filtered and recrystallized from ethanol to yield 1α-methyl-4-androstene-3β,17β,19-triol.
