Reaction Steps

A suspension of 56 mg lithiumaluminum hydride in 5 ml tetrahydrofuran is added to a solution of 200 mg 3β-hydroxy-5α-cholest-8-en-5-carbaldehyde in 20 1964ml tetrahydrofuran at room temperature. After being heated to 50° C. for two hours the reaction mixture is cooled to room temperature. 0.06 ml water, 0.06 ml of a sodium hydroxide solution (1 N) and 0.18 ml water are added subsequently. The resulting suspension is stirred for 15 minutes and filtered over anhydrous sodium sulphate. After evaporation of the solvent the residue is crystallized from ethylacetate to give 80 mg 5-(hydroxymethyl)-5α-cholest-8-en-3β-ol as a white solid.
