Versuchsvorschrift

A stirred mixture of 2-(4-tributylstannanyl-imidazol-1-yl)-6-trifluoromethyl-4-(4-trifluoromethyl-phenyl)-pyridine (Example G.12) (0.570 g, 0.88 mmol), 2-chloro-thiazole-5-sulfonic acid tert-butylamide (Example H.1) (0.265 g, 0.99 mmol), tetrakis(triphenylphosphine)palladium (0.061 g, 0.046 mmol) in toluene (6 mL) was heated under reflux conditions for 16 h. Cooled to rt, some precipitate occurred, diluted with toluene (˜5 mL), added heptane, filtered the precipitate off, washed with toluene/heptane, dried in HV to give the title compound as a white solid (220 mg, 43%). MS (ISP) 576.3 [(M+H)+]; mp 252° C.
