実験手順

4-fluoro-3-trifluoromethylphenylacetic acid (45 mg, 0.20 mmol) was dissolved in dichloromethane and cooled to 0° C. Oxalyl chloride (18 μL, 0.20 mmol) was added, then after 5 min, dimethylformamide (1.6 μL, 0.02 mmol) was added. The reaction stirred at 0° C. for 30 min and room temperature for 1 h. The solution was added slowly to a mixture of D5 (55 mg, 0.12 mmol) and triethylamine (50 μL, 0.36 mmol) in dichloromethane at −78° C. This stirred for 30 min, then was washed with saturated aqueous sodium bicarbonate and brine. It was dried over magnesium sulfate, filtered, and concentrated in vacuo. Purified by reverse-phase HPLC to yield 49 mg of a colorless solid, 3. MS (MH+): 669.1. 1H NMR (500 MHz; CDCl3; T=298 K): δ 7.47-7.02 (m, 7H), 5.74-5.42 (m, 1H), 5.30-5.04 (m, 1H), 4.63-4.31 (m, 2H), 4.09-3.86 (m, 3H), 3.75-3.59 (m, 3H), 2.81-2.60 (m, 1H), 2.60-2.43 (m, 5H), 2.18 (m, 3H), 1.93 (broad s, 2H), 1.46 (t, 3H, J=6.7 Hz), 1.30 (t, 3H, J=7.7 Hz) ppm.
