Reaction Steps

1′-Cyano-5′-(4,4′-dimethoxytrityl)thymidine in anhydrous pyridine is added to a stirred solution of t-butyldimethylchlorosilane (1.5 equivalents) and imidazole (3.0 equivalents) in anhydrous pyridine at 0° C. The resulting reaction mixture is stirred at room temperature overnight. Pyridine is evaporated and the residue dissolved in ethyl acetate, washed with brine. The crude is directly used for the next reaction.
