Procedure

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%.
