Procedure

To a 100-mL round-bottomed flask containing 4-chloro-6-(4-trifluoromethyl-phenyl)-pyrimidine, (Example 2(a), Method A), (0.30 g, 1.2 mmol) and 8-hydroxyquinoline (0.17 g, 1.2 mmol, Aldrich) in DMF (5 mL), was added NaH (56 mg, 1.4 mmol, 60% in mineral oil, Aldrich) at room temperature and the mixture was then stirred at room temperature for 48 h. After the solvent was removed in vacuum, EtOAc (25 mL) was added to the residue, and the mixture was washed with water (2×15 mL), dried over Na2SO4, filtered, and concentrated in vacuum. Silica gel chromatography (4:1 hexanes/EtOAc) afforded the title compound as a white solid. Mp: 155–157° C. MS (ESI, pos. ion) m/z: 368 (M+1). Anal. Calcd for C20H12F3N3O: C, 65.40; H, 3.29; N, 11.44. Found: C, 65.29; H, 3.25; N, 11.41.
