Procedure

A stirred mixture of 4-(4-fluoro-phenyl)-2-(4-tributylstannanyl-imidazol-1-yl)-6-trifluoromethyl-pyrimidine (Example G.14) (0.34 g, 0.57 mmol), commercially available 5-bromothiophene-2-N-tert-butylsulfonamide (0.19 g, 0.63 mmol), tetrakis(triphenylphosphine)palladium (0.039 g, 0.033 mmol) in toluene (5 ml) was heated under reflux conditions for 15 h, hexane (10 ml) was added and the mixture was stirred at RT for 1 h. The precipitate was collected by filtration and further purified by flash chromatography on silica gel (ethyl acetate/heptane) to yield 5-{1-[4-(4-fluoro-phenyl)-6-trifluoromethyl-pyrimidin-2-yl]-1H-imidazol-4-yl}-thiophene-2-sulfonic acid tert-butyl amide (0.37 g) as a white solid.
