실험 절차
A solution of 17β-hydroxy-7α-methyl-estr-5-en-3-one acetate dissolved in tetrahydrofuran is purged with nitrogen and slowly added to a suspension of lithium tertiarybutoxyaluminum hydride also purged with nitrogen. The mixture is stirred at room temperature for about 16 hours and excess hydride is destroyed by cautiously adding a solution of sodium potassium tartrate. The solid which forms is removed by filtration and the filtrate is extracted with methylene chloride. The combined methylene chloride extracts are washed with water, dried and concentrated under vacuum. Recrystalization of the residue from acetone-hexane yields the desired 7α-methyl-estr-5-ene-3β,17β-diol acetate.
