Reaction Steps

To a solution of (3-bromo-5-(5-(trifluoromethyl)pyridin-2-yloxy)phenyl)methanol (5.5 g, 15.8 mmol) in dry THF (30 mL) cooled to 0° C. was added thionyl chloride (3.22 mL, 44.3 mmol) dropwise. The reaction was warmed to RT and stirred for 2 h. The reaction mixture was then cooled and water was added. The mixture was extracted with ethyl acetate three times. The organic layer was washed with saturated NaHCO3 solution and brine, dried over Na2SO4, and evaporated to dryness to give the title compound (4.7 g). 1H NMR (500 MHz, CDCl3): δ 8.44 (s, 1H), 7.93 (d, J=8.5 Hz, 1H), 7.43 (s, 1H), 7.29 (s, 1H), 7.15 (s, 1H), 7.05 (d, J=8.5 Hz, 1H), 4.54 (s, 2H).
