Reaction Steps

2-Amino-4,6-dichloro pyrimidine (0.041 g, 0.25 mmol), 2,2,2-trifluoro-1-[2-(3-phenyl-pyrazol-1-yl)-phenyl]-ethanol (0.070 g, 0.22 mmol), and NaH (0.012 g, 0.31 mmol) were added to anhydrous THF (7 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 (0.04 ml). The reaction mixture was concentrated to give crude 4-chloro-6-{2,2,2-trifluoro-1-[2-(3-phenyl-pyrazol-1-yl)-phenyl]-ethoxy]-pyrimidin-2-ylamine (0.110 g, >90% pure by LCMS), which was directly used in the following step.
