To a solution of 3α-acetylthio-6-methyleneandrostane-17-one (210 mg) in MeOH (3 mL), 1N NaOH (0.6 mL) was added. After 1 h at room temperature 5% NaH2PO4 aqueous solution was added and the mixture extracted with Et2O (2×20 mL). The combined organic extracts were washed with brine, dried over Na2SO4 and evaporated to dryness to give 3α-mercapto-6-methyleneandrostane-17-one (185 mg, 100%).
