Reaction Steps

BnBr (1.35 mL, 11.286 mmol) was added to a solution of diflunisal (2.0 g, 7.99 mmol) in TBAF (10 mL, 1 M solution in THF) and the reaction mixture was stirred at r.t. overnight (18 h). The organic layer was poured into H2O (15 mL) and extracted with EtOAc (40 mL). It was dried over Na2SO4 (anhydrous), filtered and concentrated. The crude residue was flash chromatographed on SiO2 (hexanes) to furnish 2.09 g of benzyl 2′,4′-difluoro-4-hydroxybiphenyl-3-carboxylate (white solid, yield: 77%).
