2-Fluorophenol → HCID 178521642, compound

Participants

Reaction Steps

To a solution of (4S,2R,3R,5R)-2-hydroxymethyl-5-[6-(tetrahydrofuran-3-ylamino)-purin-9-yl]-tetrahydrofuran-3,4-diol acetonide (500 mg, 1.33 mmol), 2-fluorophenol (179.4 mg, 1.6 mmol), and triphenylphospine (418.3 mg, 1.6 mmol) in anhydrous tetrahydrofuran (20 mL), DIAD (diisopropylazodicarboxylate, 320 μL, 1.6 mmol) was added and heated to reflux for 16 hours. The reaction mixture was cooled to room temperature and the solvent evaporated. The residue was purified by column chromatography (eluting with ethyl acetate: hexane 50:50) to give (4S,2R,3R,5R)-2-(2-fluorophenoxy)methyl-5-[6-(tetrahydrofuran-3-ylamino)-purin-9-yl]-tetrahydrofuran-3,4-diol acetonide as a pure white solid.
