Procedure

Alternatively, tetrabutylammoniumfluoride (TBAF 1.0 N in THF 13 uL, 3.3 mg, 0.013 mmol) was added to a mixture of 3-methyl-biphenyl-2-carboxaldehyde (0.25 g, 1.27 mmol) and trifluoromethytrimethyl silane (0.25 g, 1.53 mmol), in THF (1.5 ml) at 0° C. The reaction was warmed to room temperature and stirred for 4 hours. HCl (3.0 N, 2.0 ml) was added, and the mixture was stirred for 3 hours. The mixture was concentrated, dissolved in methylene chloride, filtered through silica gel, and concentrated to give 0.15 g of 2,2,2-trifluoro-1-(3′-methylbiphenyl-2-yl)ethanol.
