실험 절차

17β,19-Dihydroxy-1α,7α-dimethyl-4-androsten-3-one diacetate is dissolved under nitrogen in a sodium methoxide methanol solution at 0° C. and stirred at room temperature for 2 hours. The solution is poured onto water and the solid collected by filtration. Recrystallization from acetonitrile yields the desired 17β,19-dihydroxy-1α,7α-dimethyl-4-androsten-3-one.
