    • 8 (0.978 g, 5.00 mmol) in ethyl acetate (4 mL). The mixture was stirred at 0 °C for 5 h and the precipitate was filtered off. The filtrate was evaporated to dryness under reduced pressure. The crude product was purified by silica gel chromatography using a gradient of ethyl acetate (10-40%) in hexane as an eluent. The fractions were combined and concentrated to dryness under reduced pressure to give AZBnOH (0.944 g, 71%) as a yellow oil.

    • 2 with 0.5% triethylamine as an eluent. The fractions containing dinucleoside phosphate 6 were combined and concentrated to dryness. Excess triethylamine was removed by repeated coevaporation with toluene and concentrated to dryness under reduced pressure to give 6 as a colorless foam.
