実験手順

A stirred mixture of 4-(3,4-dichloro-phenyl)-2-(4-tributylstannanyl-imidazol-1-yl)-6-trifluoromethyl-pyrimidine (Example G.6) (0.46 g, 0.71 mmol), commercially available 5-bromothiophene-2-N-tert-butylsulfonamide (0.23 g, 0.78 mmol), tetrakis(triphenyl-phosphine)palladium (0.049 g, 0.042 mmol) in toluene (8 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 dried to yield 5-{1-[4-(3,4-dichloro-phenyl)-6-trifluoromethyl-pyrimidin-2-yl]-1H-imidazol-4-yl}-thiophene-2-sulfonic acid tert-butyl amide (0.34 g) as a white solid.
