PROCEDURE

实验过程

In 2.0 ml of acetone is dissolved 0.26 g of leucic acid, and 1.0 ml of 2N-NaOH is added, followed by addition of 0.44 g of 16β-ethyl-17β-bromoacetoxy-4-estren-3-one and 15 ml of DMF. The mixture is refluxed for 3 hours, and thereafter treated in the same manner as Example 26. The reaction mixture is then subjected to column chromatography. Following passage of 50 ml of diisopropyl ether-n-hexane (1:1), elution is carried out with 200 ml of diisopropyl ether. The eluate is evaporated under reduced pressure to remove the solvent, giving 0.475 g of the above-identified compound as a viscous oil.
