Procedure
A solution of 1-O-acetyl-2,3,5-tri-O-benzoyl-β-D-ribofuranose (500 mg, 0.99 mmol), 3-trifluoroacetamidophenol (407 mg, 1.98 mmol) from Stage 1 and boron trifluoride diethyletherate (1.41 g, 9.93 mmol, 1.25 ml) in a mixture of dry dichloromethane (10 ml) and dry tetrahydrofuran (30 ml) was stirred at room temperature under argon for 7 days. Work-up as in Stage 1 of Example 1 and purification by flash chromatography on silica gel (2% acetone in toluene as eluant) gave the title compound as a colourless solid (166 mg. 21%).
