Abstract
4-Trifluoroacetamidobenzotriazole (I) was synthesized by acylation of 4-aminobenzotriazole with trifluoroacetic anhydride under mild conditions in pyridine. The silver salt (II) of I was obtained by treatment of base I with an aqueous alcohol solution of AgNO3. Condensation of silver salt II with 1-bromo-2,3,4-tri-O-acetyl-D-ribopyranoside leads to 4-trifluoroacetamidobenzotriazole N2-2,3,4-tri-O-acetyl-β-D-ribopyranoside (III). The structure of nucleoside III was confirmed by its IR, UV, and PMR spectra.
