実験手順: Alternatively, 1-(4-bromophenyl)-2,2,2-trifluoroethanol (0.98 g, 3.86 mmol), m-tolylboronic acid (0.63 g, 4.63 mmol), Pd(PPh3)2Cl2 (0.16 g, 0.232 mmol Pd), Na2CO3 (0.90 g, 8.49 mmol), AcCN (10 mls), and H2O (10 mls) were combined and heated in the microwave at 150° C. for 10 minutes. The reaction was shown complete by TLC (CH2Cl2). The mixture was cooled, concentrated, slurried in CH2Cl2, filtered, and chromatographed over silica gel (CH2Cl2) to give 0.80 g of 2,2,2-trifluoro-1-(3′-methylbiphenyl-2-yl)ethanol. Yield: 79%. The mixture was cooled concentrated filtered chromatographed over silica gel (CH2Cl2)

実験手順: To 4′-bromo-2,2,2-trifluoroacetophenone (5.0 g, 19.76 mmol) in THF (50 mls) at 0° C. was added NaBH4 (1.5 g, 39.52 mmol). The mixture was warmed to room temperature and stirred for 1 hour. The reaction was complete by TLC (CH2Cl2). The mixture was quenched with H2O, rotary evaporated to remove most of the THF, and extracted 2 times with CH2C2. The organics were combined, washed with brine, concentrated to a small volume and filtered through a plug of silica gel. The silica was washed with CH2Cl2 to elute the product, and the resulting solution was concentrated to give 4.65 g of 1-(4-bromophenyl)-2,2,2-trifluoroethanol. Yield: 92%.

実験手順: To Pd(PPh3)4 (2.1 g, 1.823 mmol) was added 3-fluorophenylmagnesium bromide (55 mls, 1.0 M in THF, 55 mmol) at 0° C. over 15 minutes. The ice bath was removed and the mixture was stirred for 30 minutes. 1-(4-Bromophenyl)-2,2,2-trifluoroethanol (4.65 g, 18.23 mmol) in THF (50 mls) was added over 10 minutes. The mixture was heated to reflux for 3 hours and was shown complete by LC (Sunfire column, TFA). The mixture was cooled, quenched with H2O, rotary evaporated to remove most of the THF, and extracted 3 times with CH2Cl2. The organics were combined washed with brine, dried over MgSO4, and concentrated. Chromatography (SiO2, CH2Cl2) gave 4.64 g of 2,2,2-trifluoro-1-(3′-fluorobiphenyl-4-yl)ethanol. Yield 94%. The ice bath was removed The mixture was heated to reflux for 3 hours The mixture was cooled quenched with H2O rotary evaporated to remove most of the THF extracted 3 times with CH2Cl2 The organics were combined washed with brine dried over MgSO4 concentrated
