Reaction Steps
To a solution of 1.0 g of 3β-(2-hydroxyethylthio)-androst-5-en-17-one in 20 ml of dimethylformamide, 1.7 g of imidazole and 2.0 g of t-butyldimethylsilyl chloride were added at 0° C. After 12 hrs the mixture was poured into water and extracted with ethyl acetate. The organic layer was dried over sodium sulfate and evaporated to dryness under reduced pressure to give 1.2 g of crude 3β-(2-tert-butyldimethylsilyloxyethythio)-androst-5-en-17-one.
