Triethylamine → HCID 10254259, compound

Participants

Reaction Steps

To a solution of (4S,2R,3R,5R)-2-[6-(cyclopentylamino)purin-9-yl]-5-ethynyloxolane-3,4-diol (40 mg, 0.12 mmol) in tetrahydrofuran (4 mL) under nitrogen was added catalytic amounts (3 mg) of (4S,2R,3R,5R)-2-[6-(cyclopentylamino)purin-9-yl]-5-ethynyloxolane-3,4-diol (II) and copper (I) iodide, followed by 1-iodo-2-trifluoromethylbenzene (0.042 mL). Triethylamine (0.4 mL) was then added, and the mixture was stirred for 15 minutes at room temperature. The solvent was removed under reduced pressure, and the residue was purified by preparative TLC, eluting with methanol:methylene chloride (6.5:1), to yield (4S,2R,3R,5R)-2-[6-(cyclopentylamino)purin-9-yl]-5-{2-[2-(trifluoromethyl)phenyl]ethynyl}-oxolane-3,4-diol, a compound of Formula I.
