2-Amino-4,6-dichloro pyrimidine (0.074 g, 0.45 mmol), 2,2,2-trifluoro-1-[2-(3-trifluoro methyl-pyrazol-1-yl)-phenyl]-ethanol (0.140 g, 0.45 mmol), and NaH (0.022 g, 0.59 mmol) were added to anhydrous THF (10 ml) under nitrogen atmosphere. The reaction was stirred at 40-45° C. for 6 h, and then cooled to room temperature, and quenched with water (0.2 ml). The reaction mixture was concentrated to give crude 4-chloro-6-[2,2,2-trifluoro-1-[2-(3-trifluoromethyl-pyrazol-1-yl)phenyl]-ethoxy]-pyrimidine-2-ylamine (0.21 g, >90% pure by LCMS), which was directly used in the next step.
