실험 절차

A tetrahydrofuran solution (2 mL) containing 703 mg (6.14 mmol) of methanesulfonyl chloride was added dropwise to a tetrahydrofuran solution (8 mL) containing 1.07 g (4.09 mmol) of (S)-N-[4-(trifluoromethyl)phenyl]-3-hydroxypentanoic acid amide produced in Example 2 and 621 mg (6.14 mmol) of triethylamine at 0° C. for 10 minutes. After stirring at the same temperature for lhour, water (25 mL) and ethyl acetate (30 mL) were added to carry out extraction. The organic layer was washed with saturated brine, and dried with anhydrous sodium sulfate. The solvent was removed by distillation under reduced pressure to obtain (S)-N-[4-(trifluoromethyl)phenyl]-3-methanesulfonyloxypentanoic acid amide as a yellow solid (1.48 g, crude yield: 97%). 1H-NMR (CDCl3, 400 MHz/ppm): δ 1.04 (3H, t), 1.91 (2H, m), 2.73-2.87 (2H, m), 3.15 (3H, s), 5.01-5.09 (1H, m), 7.56 (2H, d), 7.66 (2H, d), 7.83 (1H, br)
