Versuchsvorschrift

1.15 g of [(2R,3R,4R,5R)-3,4-diacetyloxy-5-(6-chloro-2-iodopurin-9-yl)oxolan-2-yl]methyl acetate (Toronto Research Chemicals) was placed in 20 mL of DMF (dimethylformamide) and stirred. To this solution was added 0.42 mL of cyclopentyl amine and 10 mL of DIPEA (diisopropylethylamine). The resulting mixture was stirred overnight at room temperature. The next morning, the solvent was removed and the residue purified using a dichloromethane/methanol 20:1 column to provide (2R,3R,4R,5R)-4-acetyloxy-2-(acetyloxymethyl)-5-[6-(cyclopentylamino)-2-iodopurin-9-yl]oxolan-3-yl acetate, a compound of formula (10).
