Procedure

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) (30.3 mg, 0.048 mmol) in water (0.3 mL) and a solution of (S)-cyanomethyl 6-((R)-2-((((4-azidobenzyl)oxy)carbonyl)amino)-3-(tert-butyldisulfanyl)propanamido)-2-((tert-butoxycarbonyl)amino)hexanoate (Compound tk24) (93 mg, 0.143 mmol) in tetrahydrofuran (0.3 mL) were added to buffer A (9 mL), and the mixture was stirred at room temperature for 4.5 hours. Following lyophilization, the resulting residue was purified by reverse-phase silica gel column chromatography (0.05% aqueous trifluoroacetic acid solution/0.05% trifluoroacetic acid-acetonitrile solution) to afford (2S)-(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 6-((R)-2-((((4-azidobenzyl)oxy)carbonyl)amino)-3-(tert-butyldisulfanyl)propanamido)-2-((tert-butoxycarbonyl)amino)hexanoate (Compound tk25) (6.7 mg, 11%).
