Sodium hydride (60% oil dispersion) (2.125 g, 53.1 mmol) was added in portions to a solution of phenol (5.00 g, 53.1 mmol) in THF (100 mL) while cooling in an ice bath. After 30 min, 1,2,3-trifluoro-4-nitrobenzene (6.11 mL, 53.1 mmol) was added. The mixture was stirred at RT overnight. The reaction mixture was poured on to ice/10% aqueous HCl and extracted with ethyl acetate. The organic layer was dried over sodium sulfate and the solvent was evaporated. Chromatography of the residue (ethyl acetate:hexane) gave the crude product (10.78 g, 43%) as a yellow oil.
