Acetic acid (2R,3R,4R,5R)-3,4-diacetoxy-5-(6-chloro-2-iodo-purin-9-YL)-tetrahydro-furan-2-ylmethyl ester → 2-Iodoadenosine

Participants

Reaction Steps

6.0 g of 6-chloro-2-iodo-9-(2,3,5-tri-O-acetyl-β-D-ribofuranosyl)purine was added to 60 ml of methanol/ammonia (saturated at 0° C.) to cause reaction at a temperature of 60° C. for 17 hours in a sealed tube. The reaction solution was cooled, then degassed, and concentrated under reduced pressure. Crystallization of the residue from water afforded 3.94 g of 2-iodoadenosine (90% yield).
