Procedure

2-Amino-4,6-dichloro pyrimidine (0.074 g, 0.45 mmol), 1-[2-(3,5-dimethyl-pyrazol-1-yl)-phenyl]-2,2,2-trifluoro-ethanol (0.120 g, 0.45 mmol), 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-{1-[2-(3,5-dimethyl-pyrazol-1-yl)-phenyl]-2,2,2-trifluoro-ethoxy]-pyrimidin-2-ylamine (0.195 g, >90% pure by LCMS) which was directly used in the following step.
