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(triphenyl-phosphine)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.
