Procedure
To a solution of 0.90 g of 3β-(2-hydroxyethylthio)-17β-(3-furyl)-5β-androstan-14β-ol, in 9 ml of dry pyridine, 0.64 g of tosylchloride were added. After 5 hrs 10 ml of water and 50 ml of ethyl acetate were added. The organic phase was washed with water, dried over anhydrous sodium sulfate to give 1.2 g of 3β-(2-tosyioxyethylthio)-17β-(3-furyl)-5β-androstan-14β-ol as a colourless oil.
