반응 단계

Under a nitrogen atmosphere, a mixture of 2′-deoxyuridine dU (2.5 g, 10.95 mmol), TBSCl (7.26 g, 48.2 mmol) and imidiazole (6.56 g, 96.4 mmol) in anhydrous DMF (25 mL) was stirred at 0° C. for two hours and then warmed to room temperature over one hour. The reaction mixture was concentrated in vacuo and purified by silica gel column chromatography to yield 3′,5′-O-bis-tert-butyldimethylsilyl-2′-deoxyuridine dC.11 (4.62 g, 92%) as a white foam.
