Reaction Steps

To a suspension of nucleoside 3 (380 mg, 0.606 mmol) in MeOH (20 mL) was added K2CO3 (17 mg, 0.12 mmol) at rt. The resulting mixture was stirred 18 h at rt whereupon it was treated with HOAc (15 μL, 0.25 mmol), concentrated and submitted to HPLC purification (MeCN—H2O), affording 20 mg (10%) of the title compound 4 as a white solid after lyophilization: 1H (400 MHz, DMSO-d6) δ 8.33 (s, 1H), 6.86 (br s, 2H), 6.09 (br s, 1H), 5.19 (br s, 1H), 4.88 (br s, 1H), 4.55 (t, J=5.87, 1H), 3.97 (br s, 1H), 3.76-3.81 (m, 1H), 3.61 (br s, 2H), 1.04 (s, 3H); [M+H]+ m/z 315. Analysis calc'd for C11H14N4O5S.H2O: C, 39.75; H, 4.85; N, 16.86; S, 9.65. Found: C, 40.23; H, 4.76; N, 16.64; S, 9.45.
