実験手順

To a stirred solution of 1-[(2S,4S,5R)-5-(5-amino-2,7-dioxo-6H-thiazolo[4,5-d]pyrimidin-3-yl)-4-(trifluoromethylsulfonyloxy)tetrahydrofuran-2-yl]propyl acetate (compound 22d, 420 mg, 0.83 mmol) in DMF (7 mL) was added sodium thiomethoxide (84 mg, 1.2 mmol). After being stirred at room temperature for 2 hours, the resulting solution was diluted with EtOAc, washed with brine, dried over Na2SO4 and concentrated in vacuo to afford crude product of 1-[(2S,4R,5R)-5-(5-amino-2,7-dioxo-6H-thiazolo[4,5-d]pyrimidin-3-yl)-4-methylsulfanyl-tetrahydrofuran-2-yl]propyl acetate (compound 22e), which was used in next step without further purification. MS obsd. (ESI−) [(M−H)−]: 399.
