실험 절차

2′-O-Phthalimidoethyl-5′-O-DMT-5-methyluridine (3, 21.1 g, 0.029 mol) was dissolved in methanol (500 mL). Anhydrous hydrazine (4.9 mL, 0.15 mol) was added and the solution was heated to reflux. TLC after 3 h indicated a complete reaction. The residue was purified by chromatography on silica gel using methanol and then methanol-ammonium hydroxide (98:2) to give 4 (12.4 g, 70%). The material was completely soluble in methylene chloride and traces of silica from leaching of the column were removed by filtration at this stage and reevaporating the solution.
