To a solution of 3-bromophenol (5 g, 27.54 mmol) and 2-chloro-5-(trifluoromethyl)pyridine (4.52 g, 26.16 mmol) in DMF (30 mL) was added K2CO3 and the mixture was refluxed at 110° C. overnight. Distilled water (30 mL) and diethyl ether (30 mL) were added and the mixture was stirred for 30 min. The ether layer was dried over Na2SO4 and concentrated to give pure pure title compound (8.0 g). 1H NMR (500 MHz, CDCl3): δ 7.0 (d, 1H, J=10 Hz), 7.1 (d, 1H, J=1.5 Hz), 7.2-7.3 (m, 2H), 7.4 (d, 1H, J=8 Hz), 7.9 (m, 1H), 8.4 (s, 1H).
