実験手順
To a solution of 0.20 g of 3β-(2-tosyloxyethoxy)-17β-(3-furyl)-5β-androstan-14β-ol in 2 ml of absolute ethanol 0.15 g of 1-(2-aminoethyl)pyrrolidine were added. The solution was kept at reflux under nitrogen for 3 hrs, then 10 ml of water were added. The residue was extracted with methylene chloride, the organic layer was washed with water to neutral pH, dried over anhydrous sodium sulfate and evaporated to dryness under reduced pressure. The crude residue was purified by flash-chromatography (SiO2) using methylene chloride/methanol 95/5 as eluant to give 0.15 g of the title compound (I-ag).
