Reaction Steps
Diethyl(3-pyridyl)borane (3.23 g, 22 mmol) from Aldrich Chemical Co. Ltd. was added to a stirred solution of 17-iodo-androsta-5,16-dien-3β-ol (7.96 g, 20 mmol) in THF (120 ml) containing bis(triphenylphosphine)palladium (II) chloride (140 mg, 0.2 mmol). An aqueous solution of sodium carbonate (2M, 50 ml) was then added and the mixture heated, with stirring, by an oil bath at 80° C. for 48 h, and allowed to cool.
