Reaction Steps

A solution of 2.5 g of 17β-acetoxy-16α-ethyl-4,9,11-estratrien-3-one in 120 ml of methanol and 5 ml of water is stirred, after adding 6.0 g of potassium carbonate, for 4 hours at room temperature. The mixture is then poured into water and extracted with ethyl acetate. Crystallization of the crude product from ethyl acetate yields 1.9 g of 16α-ethyl-17β-hydroxy-4,9,11-estratrien-3-one, m.p. 139°-141° C.
