Reaction Steps

A solution of 48 g of 17β-acetoxy-7α-(5-tert-butyl-dimethylsilyloxypentyl)-estr-4-en-3-one in 350 ml of methanol is allowed to stand with 35 ml of 8 vol % sulfuric acid for 30 minutes at room temperature. The solution is diluted with diethyl ether, washed neutral with water, and dried. After the concentration by evaporation, 37.7 g of 17β-acetoxy-7α-(5-hydroxypentyl)-estr-4-en-3-one is obtained as an oil.
