Reaction Steps

Tetrabutylammonium fluoride (0.028 ml; 1.0 M solution in tetrahydrofuran) was added to a solution of 2-(5-methylthiophen-3-yl)-benzaldehyde (550 mg, 1.29 mmol) and trifluoromethyltrimethylsilane (TMSCF3) (483 μl, 3.27 mmol) in 10 ml of THF at 0° C. The formed mixture was warmed up to room temperature and stirred at room temperature for 4 hours. The reaction mixture was then treated with 10 ml of 1N HCl and stirred at room temperature overnight. The product was extracted with ethyl acetate (3×50 ml). The organic layer was separated and dried over sodium sulfate. The organic solvent was evaporated to give 650 mg of 2,2,2-trifluoro-1-[2-(5-methyl-thiophen-3-yl)-phenyl]-ethanol, yield: 87%. A mixture of 2,2,2-trifluoro-1-[2-(5-methyl-thiophen-3-yl)-phenyl]-ethanol (100 mg, 0.37 mmol), 2-amino-4,6-dichloro-pyrimidine (54 mg, 0.33 mmol), cesium carbonate (481 mg, 1.48 mmol) and 1,4-dioxane (2 ml) was heated at 110° C. overnight. The reaction mixture was cooled to room temperature; 10 ml of ethyl acetate was added. The mixture was then filtered through Celite, the filtrate was concentrated to give 90 mg of 4-chloro-6-{2,2,2-trifluoro-1-[2-(5-methyl-thiophen-3-yl)-phenyl]-ethoxy}-pyrimidin-2-ylamine, yield: 68%
