Procedure

A mixture of 5-ethyl-6-phenylthio-2,4-pyrimidinedione (0.16 g, 0.66 mmol) and (4-t-butyldimethylsilyloxymethylcyclopent-1-en-1-yl)methyl bromide (0.20 g, 0.66 mmol) in dimethylformamide (10 mmol) were heated at 50° C. for overnight in the presence of sodium bicarbonate (66 mg, 0.79 mmol). After the concentration of dimethylformamide, [(4-t-butyldimethylsilyloxymethyl cyclopent-1-en-1-yl)methyl]-5-ethyl-6-phenylthio-2,4-pyrimidinedione was obtained by the separation of the column chromatography. And then, this compound in THF (10 ml) was reacted with n-tetrabutylammoniumfluoride at room temperature for 1 hr. After the concentration of THF, the residue was separated by column chromatography to give a desirable product (35 mg).
