Vorschrift

Trifluoroacetic acid (0.5 ml) was added to (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-butoxycarbonyl)amino)-3-(tert-butyldisulfanyl)propanoate (Compound 2m-A) (40 mg, 0.045 mmol), and the mixture was stirred at room temperature for 10 minutes. The reaction mixture was concentrated under reduced pressure 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-amino-3-(tert-butyldisulfanyl)propanoate (Compound 2n-A) (45.1 mg, 100%).
