Reaction Steps

A mixture of the above 2,4,6-trichloro-5-(2,4,6-trifluorophenyl)pyrimidine (104 mg), imidazole (23 mg, 0.33 mmol), and potassium carbonate (92 mg, 0.66 mmol) in 2 mL of N,N-dimethylformamide is stirred at room temperature for 3 h. The mixture is partitioned between ethyl acetate and saturated sodium chloride. The organic layer is washed with saturated sodium chloride (×4), dried over magnesium sulfate, and concentrated. The residue is chromatographed over silica gel, eluting with a gradient of hexanes to 50% ethyl acetate in hexanes. Concentration provides 4,6-dichloro-2-(1H-imidazol-1-yl)-5-(2,4,6-trifluorophenyl)pyrimidine as a tan solid (71 mg, mp 72-74° C.). MS: m/z 345.2 (M+H).
