実験手順

A solution of 3,5-bis(trifluoromethyl)phenylacetic acid (105.3 mg, 0.387 mmol) in CH2Cl2 (5 mL) was cooled to 0° C. N,N-diisopropylethylamine (169 μL, 0.968 mmol) was added, followed by HATU (139 mg, 0.3667 mmol). The reaction was stirred at 0° C. for 2 minutes and then a solution of 1-[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methanamine (62.5 mg, 0.193 mmol) in CH2Cl2 (2 mL) was added. The reaction was stirred for 1 hour at 0° C. and then diluted with EtOAc (75 mL). The organics were washed with saturated NaHCO3 and brine (25 mL each), dried over Na2SO4, filtered, and concentrated. Purification of the residue by flash chromatography with 100% CH2Cl2 gave 2-[3,5-bis(trifluoromethyl)phenyl]-N-{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}acetamide.
