실험 절차

A mixture of 5-nitro-1-(2′,3′,5′-tri-O-benzoyl-β-ribofuranosyl)-2-pyridone (10, R=Bz, Y=H, Z=CH; 100 mg, 0.17 mmol) and saturated methanolic ammonia (10 mL) was stirred at room temperature for 12 h. The mixture was concentrated to dryness, and the residue triturated with EtOH to precipitate 10 (R=Y=H, Z=CH), which was collected and recrystallized from water (37 mg, 81%) as a white solid. 1H NMR (DMSO-d6+D2O) δ 3.64 (m, 1H), 3.90 (m, 1H), 4.01 (m, 3H), 5.89 (s, 1H), 6.48 (d, J=10.4 Hz, 1H), 8.12 (dd, J=3.2, 10 Hz, 1H), 9.65 (d, J=3.2 Hz, 1H).
