3-benzoyl-benzoic acid methyl ester (653 mg, 2.72 mmol) was stirred in trifluoroacetic acid (3 mL) with triethylsilane (1.3 mL, 8.15 mmol) at room temperature for 22 h. The reaction mixture was diluted with ethyl acetate and washed with an aqueous NaHCO3 solution. The organic layer was dried over MgSO4, filtered and concentrated. The resultant oil was subjected to column chromatography (25 hexanes: 1 ethyl acetate) to provide 3-benzyl-benzoic acid methyl ester (589 mg, 2.6 mmol) as an oil.
