実験手順

To a solution of [2-amino-5-(trifluoromethyl)benzyl][3,5-bis(trifluoromethyl)benzyl]amine (Example 3) (270 mg, 0.65 mmol) in methylene chloride at 0° C., acetic anhydride (0.061 mL, 0.65 mmol) in methylene chloride and then triethylamine were added (0.018 mL, 0.13 mmol). The solution was stirred for 0.5 hours at 0° C. This solution was washed with saturated sodium bicarbonate, dried over anhydrous sodium sulfate, filtered and concentrated. The title compound was purified by column chromatography using 40% EtOAC/hexane. 1H NMR (CDCl3, 500 MHz) δ 7.80 (s, 1H), 7.56 (s, 2H), 7.30 (d, J=8.5 Hz, 1H), 7.04 (s, 1H), 6.65 (d, J=8.5 Hz, 1H), 4.67 (s, 2H), 4.65 (s, 2H), 2.22 (s, 3H).
