To a cooled (0° C.) solution of 2-fluoro-N-methoxy-N-methyl-3-trifluoromethyl-benzamide (5.0 g, 20 mmol) in THF (50 ml) was added phenethyl magnesium chloride (50 ml of 1.0M in THF) and the reaction was warmed to r.t. After 2 hr, the reaction was poured into 2N HCl and extracted with ether. The organic layer was dried (MgSO4), and concentrated and the product was purified by column chromatography (eluent 5% EtOAc/Hexane) to give 1-(2-fluoro-3-trifluoromethyl-phenyl)-3-phenyl-propan-1-one as a clear oil (4.8 g). MS (ES) m/z 297.0.
