To a mixture of 4-chloro-6-(4-trifluoromethyl-phenyl)-pyrimidine, (Example 2(a), Method A), (0.10 g, 0.39 mmol) and 2,8-quinolinediol (0.075 g, 0.46 mmol, Fluka) in acetonitrile (5 mL) was added 1,8-diazabicyclo[5.4.0]undec-7-ene (0.069 mL, 0.46 mmol, Aldrich). The mixture was heated to reflux for 6 h, allowed to cool to room temperature, and diluted with EtOAc. The solids were filtered, washed with EtOAc and dried in vacuum for 16 h to yield the title compound as long white needles. Mp: 312° C., MS (ESI, pos. ion) m/z: 384 (M+1).
