実験手順

A solution of 1-phthalimido-4-p-toluenesulfonyl-6,6-difluoro-8-benzyloxy-4-aza-octane (9.5 g, 17.1 mM) and trimethylsilyl iodide (2.7 mL, 10% excess) in dry dichloromethane is stirred overnight at room temperature under nitrogen. Triethylamine (3 g) is added, and stirring is continued for 1 hour at room temperature. Following the addition of more dichloromethane, the reaction mixture is washed with 1N HCl (twice), aqueous NaHSO3 (twice), brine (twice), and dried (Na2SO4). The solvents are removed by evaporation to yield an oil. This oil is dissolved in methanol and 1 mL of a 9N solution of HCl in methanol is added. The mixture is evaporated and stripped twice with CCl4 to provide an oil, which upon scratching with ether/petroleum ether yields 1-phthalimido-4-p-toluenesulfonyl-6,6-difluoro-8-hydroxy-4-aza-octane as slightly violet crystals: 6.8 g (85%).
