실험 절차

NaH (80 mg, 60%, 3.0 mmol) was added to a solution of 1-(2-trifluoromethylphenyl)-2,2,2-trifluoro-ethanol (244 mg, 1 mmol) in 10 ml of anhydrous THF. The mixture was stirred for 20 minutes, 2-amino-4,6-dichloro-pyrimidine (164 mg, 1 mmol) was added and then the reaction mixture was heated at 70° C. for 1 hour. After cooling, 5 ml water was added and ethyl acetate (20 ml) was used to extract the product. The organic layer was dried over sodium sulfate. The solvent was removed by rotovap to give 267 mg of 4-chloro-6-[2,2,2-trifluoro-1-(2-trifluoromethylphenyl)-ethoxy]-pyrimidin-2-ylamine, yield 71%.
