Participants

Reaction Steps

A slurry of 5′-O-(4,4′-dimethoxytrityl)-3′-p-toluen-sulfonyloxymethylthymidine (0.40 g; 0.55 mmol) and NaN3 (0.11 g; 1.65 mmol) in anhydrous DMF (3 ml) was heated at 50° C. for 3 days. The reaction mixture was cooled to room temperature, diluted with EtOAc (30 ml), and washed with water (3×40 ml) , then with 10% NaHCO3 (3×40 ml). The organic layer was dried over Na2SO4, concentrated and purified by chromatography on silica (EtOAc-Hexanes, 1:1) to yield 0.30 g (92%) of 5′-O-(4,4′-dimethoxytrityl)-3′- C-azidomethylthymidine as a colorless powder.
