Reaction Steps
A solution of 30 g of 17β-hydroxy-1α-methyl-5α-androstan-3-one in 300 ml of toluene and 90 ml of ethylene glycol is combined with 900 mg of p-toluenesulfonic acid and stirred for 6 hours with gradual removal by distillation. After cooling, the reaction solution is mixed with 3 ml of pyridine, diluted with diethyl ether, and washed with water. After evaporation, 35 g of 3,3-ethylenedioxy-1α-methyl-5α-androstan-17β-ol is obtained.
