Versuchsvorschrift

To a 250-mL, round-bottomed flask containing 4-chloro-6-(4-trifluoromethyl-phenyl)-pyrimidine, (Example 2(a), Method A), (2.5 g, 9.7 mmol) and 7-hydroxyquinoline (2.0 g, 14 mmol, Acros) in DMF (30 mL), was added NaH (5.4 g, 14 mmol, 60% in mineral oil, Aldrich) at room temperature The solution was then stirred at room temperature for 4 h. After the solvent was removed in vacuum, EtOAc (100 mL) and water (50 mL) were added to the residue. The solid precipitate was filtered and the filtrate was poured into a separatory funnel. The organic layer was separated, combined with the previously isolated solid, concentrated in vacuum, and purified by silica gel chromatography (2:1 hexanes/EtOAc). The purified product was dissolved in acetone (30 mL) and MeOH (10 mL), and to the solution was added water (30 mL) in small portions. The precipitated solid was filtered, washed with water (5 mL), and dried under vacuum at 50° C. for 48 h to furnish the title compound as a white solid. Mp: 178-180° 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, 65.42; H, 3.23; N, 11.43.
