Procedure

In a nitrogen stream, triethylsilane (0.19 ml, 1.21 mmol) and a boron trifluoride-diethyl ether complex (0.14 ml, 1.11 mmol) were added to a solution of (3R,4R,5S,6R)-3,4,5-trisbenzyloxy-6-benzyloxymethyl-2-[3-(5-fluorobenzo-[b]thiophen-2-ylmethyl)-naphthalen-1-yl]tetrahydropyran-2-ol (770 mg, 0.93 mmol) in methylene chloride (10 ml) at 0° C. The reaction mixture was stirred at room temperature for two hours, and then a saturated sodium hydrogen carbonate aqueous solution was added. The obtained mixture was extracted with methylene chloride, and the organic layer was washed with a saturated sodium chloride aqueous solution and then dried with sodium sulfate. The solvent was distilled under reduced pressure, and the obtained residue was purified by silica gel column chromatography [developing solution=ethyl acetate:n-hexane (1:20)] to obtain the title compound (550 mg, 73%).
