To an oven-dried, 50-mL, round-bottomed flask were added 7-hydroxyquinoline (Aldrich) (87 mg, 0.6 mmol) and DMF (1 mL). The solution was place under nitrogen, and NaH (24 mg, 0.6 mmol) was added in one portion. After stirring for 10 min, 2-chloro-4-(4-trifluoromethylphenyl) pyridine (Example 410 (c), 129 mg, 0.5 mmol) was added. The reaction mixture was heated in a 155° C. oil bath for 72 h. After cooling to room temperature, the reaction mixture was partitioned between EtOAc and brine. The aqueous layer was extracted with EtOAc and the combined organic layers were dried over Na2SO4, concentrated in vacuo. The crude material was purified on a Biotage 40 S column (3:1 hexanes:EtOAc) to give the title compound as an off-white solid. MS (ESI, pos. ion) m/z: 367 (M+1). Mp: 156.5-158.5° C.
