Procedure

Ethylene glycol (20 ml.) and p-TSA (5 mg.) is added to 17β-hydroxy-17α-methyl-5α-androstan-3-one (sold by Steraloids, Inc., Wilton, N.H., 3.0 g.) in methylene chloride (20 ml.). The mixture is heated on a steam bath until most of the methylene chloride is removed. The remainder of the methylene chloride is removed on a rotary evaporator. The mixture is cooled and a small amount of a sodium bicarbonate solution and water are added and the mixture filtered. The filtered solids are washed and dried to give the title compound, NMR (CDCl3), 0.83, 0.84, 1.20 and 3.29δ.
