Versuchsvorschrift

NaH (60%, 120 mg, 3.0 mmol) was added to a solution of 2,2,2-trifluoro-1-phenyl-ethanol (350 mg, 2.03 mmol) in 5 ml of THF. The mixture was stirred for 20 minutes at room temperature. 4,6-Dichloro-pyrimidine (300 mg, 2.03 mmol) was added and then the reaction mixture was heated at 70° C. for 1 hour. After cooling, the THF was evaporated to provide a residue, which was dissolved in 15 ml of EtOAc, and then washed with water, and dried over sodium sulfate. The solvent was removed by rotovap to give 550 mg of 4-chloro-6-(2,2,2-trifluoro-1-phenyl-ethoxy)-pyrimidine, yield 95%.
