Reaction Steps

Add t-butyldimethylsilyl chloride (5.49 g, 36.4 mmol), 4-dimethylaminopyridine (0.21 g, 1.74 mmol) and triethylarmine (5.32 mL, 38.14 mmol) to a stirred solution of 3β-hydroxyandrosta-5,15-dien-17-one (M81, 10.00 g, 34.8 mmol) in anhydrous DMF (175 mL) under nitrogen. Stir the resultant suspension at room temperature for 3 days and then pour into rapidly stirred water (750 mL). Filter the resultant suspension and crystallize the white solid to give 3β-[[(1,1-dimethylethyl)dimethylsilyl]oxy]androst-5,15-dien-17-one (M82).
