PROCEDURE

实验过程

To a solution of (2R,3R,4R,5R)-4-acetyloxy-2-(acetyloxymethyl)-5-[6-(cyclopentylamino)-2-iodopurin-9-yl]oxolan-3-yl acetate (0.9 g, 1.53 mmol) in N,N-dimethylformamide (40 ml) was added tributyltin cyanide (0.58 g, 1.84 mmol) and tetrakis(triphenylphosphine)palladium (0.27 g, 0.23 mmol), and the mixture was stirred at 120° C. f overnight. Solvent was removed under reduced pressure, and the residue was dissolved in ethyl acetate and filtered through celite. The solvent was removed under reduced pressure, and the residue was chromatographed on silica gel, eluting with a mixture of ethanol/hexane 1:1, to provide (2R,3R,4R,5R)-4-acetyloxy-2-(acetyloxy-methyl)-5-[2-cyano-6-(cyclopentylamino)purin-9-yl]oxolan-3-yl acetate (0.65 g).
