실험 절차

To a solution of a mixture of 4-methyl-2-{5-piperidin-4-yl-4′-trifluoromethyl-biphenyl-3-yl)-pentanoic acid ethyl ester and methyl ester (68b) (40 mg, 0.09 mmol) in 1,2-dichloroethane (2.0 mL) was added 3-fluoro-5-trifluoromethyl-benzaldehyde (19 mg, 0.10 mmol) and sodiumtriacetoxyborohydride (25 mg, 0.12 mmol). The mixture was stirred for 14 h at room temperature. The reaction was quenched with water and extracted with dichloromethane. The organic was washed with saturated aqueous NaHCO3 solution and brine. The organic fraction was dried (MgSO4) and concentrated in vacuo. The crude mixture contained 2-{5-[1-(3-fluoro-5-trifluoromethyl-benzyl)-piperidin-4-yl]-4′-trifluoromethyl-biphenyl-3-yl}-4-methyl-pentanoic acid ethyl ester and methyl ester. Calcd for C33H34F7NO2 (M+H) 610.62, Found 610.30 (methyl ester) and Calcd for C34H36F7NO2 (M+H) 624.64, Found 624.24 (ethyl ester).
