Acetic Acid → 19-Hydroxy-1beta-methyl-4-androsten-3,17-dione

Participants

Reaction Steps

19-Hydroxy-1β,2β-methylene-4-androstene-3,17-dione, zinc powder, and acetic acid are heated to their reflux temperature for a period of about 1 hour. Upon cooling of the reaction mixture, benzene is added and the resulting suspension filtered. The filtrate is evaporated to dryness under vacuum and the residue remaining is chromatographed on a silica gel column and eluted with methylenechloride. The eluate is evaporated to dryness and the residue is crystallized from an acetone-hexane solution to yield 19-hydroxy-1β-methyl-4-androstene-3,17-dione.
