To a mixture of 0.54 g of 1-O-acetyl-5-O-(tert-butyldiphenylsilyl)-2,3-dideoxy-4-thioribofuranose (prepared by the procedure of J. A. Secrist et al., J. Meal. Chem.,1992, 35, 533) in 8 ml of tetrahydrofuran and 0.6 g of acetic acid is added 4 mmol of 1M n-tetrabutylammonium fluoride solution. The reaction is stirred for 5 hours and then another portion of 0.10 g of acetic acid and I mmol of n-tetrabutylammonium fluoride is added and the reaction is stirred for 1 hour. Cold potassium dihydrogen phosphate and ethyl acetate are added to the reaction mixture, followed by an aqueous workup. Purification by chromatography gives 0.164 g of the desired product.
