Procedure
Under a nitrogen atmosphere, dimethylsulfide (1.72 ml) and a boron trifluoride-diethyl ether complex (0.86 ml, 6.8 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 (550 mg, 0.68 mmol) in methylene chloride (15 ml) under cooling with ice. The reaction mixture was stirred at room temperature for 2.5 days, then a saturated sodium hydrogen carbonate aqueous solution was added under cooling with ice and the mixture was extracted with methylene chloride. The organic layer was washed with a saturated sodium chloride aqueous solution and then dried with sodium sulfate, and thereafter the solvent was distilled under reduced pressure. The obtained residue was purified by silica gel column chromatography [developing solution=methylene chloride:methanol (40:1)] to obtain the title compound (140 mg, 46%).
