Reaction Steps
2-(4-Trifluoromethyl-1H-imidazol-2-yl)-phenylamine (0.200 g, 0.880 mmol) and 2,4,5-Trichloro-pyrimidine (0.161 g, 0.880 mmol) were dissolved in N,N-Dimethylformamide (5.0 mL) and the reaction was heated at 50° C. and was allowed to stir overnight. The reaction mixture was poured over saturated ammonium chloride, and organics were extracted with ethyl acetate/dichloromethane. Combined organics were dried over sodium sulfate, filtered and reduced en vacuo. The crude mixture was purified by Isco flash column chromatography (Hexane/Ethyl Acetate). Combined fractions were reduced en vacuo to afford 220 mg (67%) of the desired product.
