Reaction Steps

8α,9α-Epoxycholest-5-en-3β-ol (200 mg) is dissolved in 13 ml diethylamine at −20° C. Lithium (100 mg) is added in small portions. The reaction mixture is stirred for 3 hours. After aqueous work-up, a crude product (207 mg) is isolated. Crystallization from diisopropylether yields cholest-5-ene-3β,9α-diol (62 mg).
