To a solution of (4-{[tert-butyl(diphenyl)silyl]oxy}cyclohexyl)methanol (7.38 g) and triethylamine (8.37 mL) in DMSO (50 mL) was added sulfur trioxide pyridine complex (9.56 g). The reaction mixture was stirred at room temperature for 3 hr and extracted with diethyl ether and water. The obtained organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel chromatography (hexane/ethyl acetate) to give the title compound (5.83 g).
