Reaction Steps

N-{8-[17β-acetoxy-3-benzoyloxyestra-1,3,5(10)-trien-7α-yl]octyl}-3,3-dimethyl-7-nitrobenzisoselenazoline (115 mg, 0.15 mmol) is dissolved in 2 ml of THF and 1 ml of methanol. To the obtained mixture is then added an aqueous solution of NaOH (1 ml, 1N, 1.0 mmol). The reaction medium is stirred at room temperature for 22 hours, then neutralized with an aqueous solution of HCl (1N). The mixture is extracted with ethyl acetate. The combined organic phases are washed with a saturated aqueous solution of NaCl, dried over MgSO4 and evaporated. The residue is purified by silica gel column chromatography (eluent:EtOAc:cyclohexane, 1:3) to provide the expected product (95 mg, 94%) as a deep red solid.
