To a solution of 2-chloro-4-nitropyridine (200 mg, 1.00 mmol) in 1,4-dioxane (6 mL) was added. (R)-1-(4-chloro-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethanol (368 mg, 1.27 mmol), and Cs2CO3 (828 mg, 2.54 mmol). The reaction was heated to 80° C. for 12 h, then cooled to RT, diluted with water, and extracted with EtOAc. The combined organic layers were dried over Na2SO4, filtered, and concentrated in vacuo. Purification by normal phase silica gel column (EtOAc/heptane) provided (R)-2-chloro-4-(1-(4-chloro-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethoxy)pyridine as an off-white solid.
