Reaction Steps

Cyanomethyl but-3-enoate (Compound 86) (0.050 g, 0.400 mmol) was added to 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 tetrabutylammonium salt (Compound 1h) (0.20 g, 0.150 mmol) in DMF (1.0 ml), and the mixture was stirred at room temperature for 1 hour. A 0.05% aqueous TFA solution was added to the reaction solution, the mixture was lyophilized, and the resulting residue was purified by preparative HPLC (0.05% aqueous TFA solution:acetonitrile) to prepare the title compound 85 (0.010 g, 10%).
