Reaction Steps

To a mixture of 4-bromo-3-(trifluoromethoxy)phenol (2.97 g, 11.6 mmol) in DMF (10 mL) was added Cs2CO3 (5.65 g, 17.3 mmol) and benzyl chloride (1.46 mL, 12.7 mmol) at RT. The reaction mixture was stirred overnight then quenched with water and diluted with EtOAc. The organic phase was washed with water (3×), brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by flash column chromatography (EtOAc/Heptane) to afford the title compound as a colorless oil (3.92 g, 98% yield). 1H NMR (METHANOL-d4) δ 7.51 (d, J=9.1 Hz, 1H), 7.40-7.45 (m, 4H), 7.34-7.40 (m, 1H), 6.97 (dd, J=2.5, 1.5 Hz, 1H), 6.82 (dd, J=9.1, 3.0 Hz, 1H), 5.06 (s, 2H).
