Reaction Steps

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%
