Versuchsvorschrift

A solution of ((2R,3S,5R)-5-(4-amino-2-oxopyrimidin-1(2H)-yl)-3-(((((2R,3S,4R,5R)-5-(6-amino-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methoxy) (hydroxy)phosphoryl)oxy)tetrahydrofuran-2-yl)methyl dihydrogenphosphate (Compound 1h) (77 mg, 0.121 mmol) in water (2.40 ml) and a solution of (R)-cyanomethyl 2-((tert-butyldisulfanecarbonyl)(methyl)amino)-3-(tert-butyldisulfanyl)propanoate (Compound 21-G) (198 mg, 0.483 mmol) in tetrahydrofuran (1.21 ml) were added to buffer A (46 ml), and the mixture was stirred at room temperature for 2 hours. Trifluoroacetic acid (0.967 ml) was then added, after which the mixture was purified by reverse-phase silica gel column chromatography (0.05% aqueous trifluoroacetic acid solution/0.05% trifluoroacetic acid-acetonitrile solution=100/0→60/40) to afford (2R)-(2R,3S,4R,5R)-2-((((((2R,3S,5R)-5-(4-amino-2-oxopyrimidin-1(2H)-yl)-2-((phosphonooxy)methyl)tetrahydrofuran-3-yl)oxy)(hydroxy)phosphoryl)oxy)methyl)-5-(6-amino-9H-purin-9-yl)-4-hydroxytetrahydrofuran-3-yl 2-((tert-butyldisulfanecarbonyl)(methyl)amino)-3-(tert-butyldisulfanyl)propanoate (Compound 2m-G) (3.8 mg, 3%).
