Procedure
To a solution of a 6α-hydroxy-17β-acetoxy-4-ethylandrost-4-en-3-one and 6β-hydroxy-17β-acetoxy-4-ethylandrost-4-en-3-one (510 mg) in acetone (34 ml) cooled at 0° C., Jones reagent (1.1 ml) was added dropwise. 5 min after completion of the addition, DCM (140 ml) was added and the mixture was washed with 10% Na2SO3 aqueous solution, 5% aqueous NaHCO3 solution, and brine. The organic phase was dried over Na2SO4, and evaporated to dryness to give 17β-acetoxy-4-ethylandrost-4-en-3,6-dione (465 g, 92%).
