Reaction Steps

To a solution of 2′-O-(5-aminopentyl)-5′-O-(4,4′-dimethoxytrityl)-adenosine (1.0 g, 1.52 mmol) in anhydrous CH3CN (8.0 mL) was added with stirring, under argon, N-(2-Cyanoethoxycarbonyl)oxy succinimide (0.43 g, 2.02 mmol) After stirring for 5 h at room temperature the reaction mixture was diluted with EtOAc (50 mL) and washed with aq saturated bicarbonate (3×20 mL) and water (20 mL), dried (Na2SO4) and evaporated to give 53 as a light yellow foam (1.1 g, 98% yield). This compound was used without further purification for the next step.
