Reaction Steps

The mixture of 2,2,2-trifluoro-1-(4-pyridin-4-yl-phenyl)ethanol (100 mg, 0.40 mmol), 2-amino-4,6-dichloropyrimidine (60 mg, 0.38 mmol), and cesium carbonate (468 mg, 1.44 mmol) was dissolved in 2 ml of 1,4-dioxane in a 50 ml sealed tube. The mixture was heated at 110° C. overnight, then was cooled to room temperature; 10 ml of ethyl acetate was added and then filtered through Celite. The filtrate was concentrated to give 120 mg of 4-chloro-6-[2,2,2-trifluoro-1-(4-pyridin-4-yl-phenyl)-ethoxy]-pyrimidin-2-ylamine, yield: 80%.
