実験手順
A solution of 4'-cyano-5'-O-acetylthymidine (0.85 g, 2.76 mM) and NH4OH (15 ml) in CH3OH (15 ml) was stirred at 24° C. for 2 hours. The solvent was removed by evaporation under pump vacuum. The residue was purified by flash chromatography on silica gel eluting with (7% CH3OH/CH2Cl2) and by preparative chromatography TLC affording 4'-cyanothymidine (300 mg, 1.12 mM). mp 238.5° C. to 242.5° C.
