반응 단계

To 200 ml of acetone-water (1:1) are added 6.0 g of 16β-ethyl-17β-bromoacetoxy-4-estren-3-one and 5.2 g of sodium n-decanoate and the mixture is refluxed for 10 hours. The solvent is distilled off under reduced pressure and the residue is extracted with 300 ml of ethyl acetate. The organic layer is separated, washed with water and saturated aqueous sodium chloride solution and dried over anhydrous sodium sulfate. The solvent is then distilled off under reduced pressure and the residue is subjected to column chromatography. Following passage of 750 ml of diisopropyl ether-n-hexane (1:9), elution is carried out with 1000 ml of a 1:1 mixture of the same solvents. The eluate is evaporated under reduced pressure to remove the solvent, giving 5.2 g of the above-identified compound as a light-yellow viscous oil.
