Procedure

To a 100-mL, round bottomed flask containing 4-chloro-6-(4-trifluoromethyl-phenyl)-pyrimidine, (Example 2(a), Method A), (0.26 g, 1.0 mmol) and 6-methoxy-2-methyl-quinolin-4-ol (0.19 g, 1.0 mmol, Ubichem) in DMF (5 mL), was added NaH (48 mg, 1.2 mmol, 60% in mineral oil, Aldrich) at room temperature The solution was then stirred at room temperature for 24 h. After the solvent was removed in vacuum, EtOAc (30 mL) was added to the residue, and the mixture was washed with brine (2×15 mL), dried over Na2SO4, filtered, and concentrated in vacuum. After the product was purified by silica gel chromatography (5:1 hexanes/EtOAc), the resulting solid was dissolved in acetone (10 mL) and MeOH (8 mL). Water (15 mL) was then added dropwise to afford a white precipitate, which was collected by filtration, washed with water (2 mL), and dried under vacuum at 50° C. for 48 h to furnish the title compound. Mp: 165–166° C. MS (ESI, pos. ion) m/z: 412; Anal. Calcd for C22H16F3N3O2: C, 64.23; H, 3.92; N, 10.21. Found: C, 64.20; H, 3.85; N, 10.14.
