実験手順

To a solution of 1-[(2S,4R,5R)-5-(5-amino-2,7-dioxo-6H-thiazolo[4,5-d]pyrimidin-3-yl)-4-hydroxy-tetrahydrofuran-2-yl]propyl benzoate (compound 26d, 4.32 g, 10.0 mmol) in DCM (60 mL) was added DMAP (2.44 g, 20 mmol) and O-phenyl chloromethanethioate (1.6 mL, 12.0 mmol) with stirring. After being stirred at room temperature for 2 hours, the resulting solution was concentrated in vacuo and the residue was purified by column chromatography on silica gel (eluting with 1:10 to 1:1 EtOAc in petroleum ether) to afford 1.9 g of 1-[(2S,4R,5R)-5-(5-amino-2,7-dioxo-6H-thiazolo[4,5-d]pyrimidin-3-yl)-4-phenoxycarbothioyloxy-tetrahydrofuran-2-yl]propyl benzoate (compound 26e). MS obsd. (ESI+) [(M+H)+]: 569.
