To a solution prepared by dissolving 7 mg (0.10 mmol) of 1-[5-O-(t-butyldiphenylsilyl)-2,3-dideoxy-2,2-di(phenylthio)-β-D-glycero-pentofuranosyl]uracil prepared in step (3) in 10 ml of anhydrous benzene, 150 μl (0.57 mmol) of hydrogenated tributyl tin and 10 mg of azobisisobutylonitrile were added, followed by subjecting the resultant solution to a reflux under heating for 48 hours under an argon gas atmosphere. After completion of the reaction, a low boiling point substances were removed by distillation under a reduced pressure so as to obtain a residue.
