実験手順

To a solution of 0.28 g of 1-(2-mercaptoethyl)pyrrolidine in 20 ml of dimethylformamide, 0.086 g of sodium hydride (60% dispersion in mineral oil) were added under nitrogen atmosphere, and the mixture stirred at room temperature for half an hr; a DMF solution of 1.0 g of 3β-(2-tosyloxyethoxy)-17β-(3-furyl)-5β-androstan-14β-ol, prepared as described in Ex. 7, was added and the mixture was stirred for another 4 hrs; the reaction mixture was quenched with water and extracted with methylene chloride. The organic layer was washed with water, dried over anhydrous sodium sulfate and evaporated to dryness under reduced pressure. The crude product was purified by flash-cromatography (SiO2) using methylene chloride/methanol 95/5 as eluant and 0.90 g of the title compound (I-ai) as a white amorphous solid.
