Reaction Steps
2-Amino-4,6-dichloro pyrimidine (0.107 g, 0.65 mmol), 2,2,2-trifluoro-1-(2-imidazol-1-yl-phenyl)-ethanol (0.157 g, 0.65 mmol), and NaH (0.03 g, 0.78 mmol) were added to anhydrous THF (10 ml) under nitrogen. The reaction was stirred at 40-45° C. for 6 h, and was 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-imidazol-1-yl-phenyl)-ethoxy]-pyrimidin-2-ylamine (0.24 g, >90% pure by LCMS), which was directly used in the following step.
