Reaction Steps

A mixture of nucleoside triester 119 (209 mg, 0.325 mmol) and MeOH (10 mL) saturated with NH3 (g) at −30° C. was stirred in a sealed tube for 48 h. The mixture was warmed to rt, depressurized, concentrated then submitted to HPLC purification (MeCN—H2O), affording 36 mg (34%) of the title compound as a white solid after lyophilization: 1H (400 MHz, DMSO-d6) δ 11.18 (s, 1H), 6.92 (br s, 2H), 5.95 (s, 1H), 5.18-5.28 (br m, 1H), 4.75 (br s, 1H), 4.53 (dd, J=11.3, 5.46, 1H), 3.95 (br s, 1H), 3.73-3.78 (m, 1H), 3.29 (br s, 2H), 1.04 (s, 3H); [M+H]+ m/z 331.
