Procedure

Dichloromethane (20 mL) and pyridine (264 μL, specific gravity: 0.978 g/cm3) were added to (±)-1-benzoyl-3-[(1S*,2R*,5S*)-1-(2-fluorophenyl)-2-hydroxymethyl-5-methoxycyclohexyl]thiourea obtained in Preparation Example 57-(6) (453 mg) according to the method of Preparation Example 18-(5). The mixture was cooled to −78° C. under a nitrogen atmosphere and stirred for 15 minutes. Trifluoromethanesulfonic anhydride (358 μL, specific gravity: 1.72 g/cm3) was slowly added to the reaction solution. After completion of the addition, the mixture was stirred for 15 minutes and then further stirred for one hour while warming to 0° C. After adding ethyl acetate, a saturated sodium bicarbonate solution was added, followed by extraction with ethyl acetate. The organic layer was sequentially washed with water and brine and dried over anhydrous magnesium sulfate. The solid was removed by filtration. After concentration under reduced pressure, the residue was purified by silica gel column chromatography to obtain the title compound (268 mg).
