실험 절차

To a stirred solution of 13.11 g (50 mmol) Ph3P, 6.99 g (47.5 mmol) phthalimide and 17.77 g (50 mmol) N6-benzoyl-2′-deoxyadenosine in 400 mL dry THF was added 9.84 mL (50 mmol) of diisopropyl azodicarboxylate under a nitrogen atmosphere. The resulting mixture was stirred for 2 h in an ice water bath and then 4 h at room temperature. After most of the THF was evaporated under reduced pressure, the oily residue was added 100 ml of dichloromethane. The precipitate, which was formed after the addition of dichloromethane, was filtered and washed with small amounts of THF/dichloromethane mixture (1:1). The filtrate was concentrated and purified with a silica gel column chromatography (dichloromethane/THF=2:1 then dichloromethane/methanol=19:1) to give 7.1 g of compound 2.
