실험 절차

To 150 ml of acetone-water (2:1) are added 1.3 g of 16β-ethyl-17β-bromoacetoxy-4-estren-3-one and 1.0 g of sodium stearate and the mixture is refluxed for 4 hours and allowed to stand at room temperature (15°-25° C.) overnight. The solvent is then distilled off under reduced pressure and the residue is extracted with 150 ml of ethyl acetate. The organic layer is separated, washed with water and saturated aqueous sodium chloride and dried over anhydrous sodium sulfate. The solvent is distilled off under reduced pressure and the residue is dissolved in 100 ml of ethanol. To the solution is added 0.3 g of activated carbon and the insoluble material is filtered off. The solvent is distilled off to give a colorless viscous oil, which is allowed to stand at room temperature (15°-25° C.) to give 1.1 g of the above-identified compound as a solid.
