実験手順
Into a Teflon container were placed (±)-methyl(16RS, 13E)-11-tert-butyldimethylsilyloxy-16-hydroxy-16-methyl-9-oxoprost-13-en-1-oate (1.89 g, 3.81 mmol) and acetonitrile (50 ml), whereby 46% hydrofluoric acid (4.5 ml) was added and stirred at room temperature for 2 h. The reaction mixture was added with water (120 ml) and extracted with methylene chloride (60 ml) two times. The combined organic layer was washed with a saturated aqueous sodium hydrogencarbonate, a saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, and concentrated in vacuo to remove solvent. The residue was purified by silica gel column chromatography [ethyl acetate/hexane (2/1)] to give 1.44 g (99% yield) of Misoprostol;
