2-Amino 4,6-dichloro pyrimidine (0.164 g, 1 mmol), 4-(2-trifluoromethyl-phenyl)-piperidine hydrochloride (0.266 g, 1 mmol), and cesium carbonate (0.684 g, 2.1 mmol) were dissolved in a mixture of 1,4-dioxane (5 ml) and H2O (5 ml) in a 20 ml microwave vial. The mixture was stirred at 210° C. for 20 minutes in a microwave reactor. Solvent was removed and the residue was dissolved in 5% methanol in CH2Cl2 (20 ml), dried over Na2SO4 and concentrated to get the crude intermediate, 4-chloro-6-[4-(2-trifluoromethyl-phenyl)-piperidin-1-yl]-pyrimidin-2-ylamine (0.42 g) which was directly used in the following step.
