The mixture was heated at 110° C. overnight. The reaction mixture was cooled to room temperature. 10 ml of ethyl acetate was added, and then the mixture was filtered through Celite. The filtrate was concentrated to give 110 mg of 4-chloro-6-[2,2,2-trifluoro-1-(2-pyridin-4-yl-phenyl)-ethoxy]-pyrimidine, yield: 76%.
