実験手順

To a solution of 2-[3,5-bis(trifluoromethyl)phenyl]-N-{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}acetamide (77.6 mg, 0.134 mmol) in THF (4.4 mL) was added BH3 (1.34 mL of a 1M solution in THF, 1.34 mmol). The reaction was stirred overnight at room temperature and then 1 N HCl (10 mL) was added. The mixture was stirred for 5 minutes and then adjusted to a slightly basic pH with 1 N NaOH. The mixture was then extracted with CH2Cl2 (4×20 mL). The organic extracts were dried over Na2SO4, filtered, and concentrated. Purification of the residue by flash chromatography with 25 to 40% EtOAc/hexanes gave {2-[3,5-bis(trifluoromethyl)phenyl]ethyl}{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}amine.
