Heptane → 5-{1-[4-Trifluoromethyl-6-(4-trifluoromethyl-phenyl)-pyridin-2-yl]-1H-imidazol-4-yl}-pyridine-3-sulfonic acid amide

Participants

Reaction Steps

A stirred mixture of 2-(4-tributylstannanyl-imidazol-1-yl)-4-trifluoromethyl-6-(4-trifluoromethyl-phenyl)-pyridine (Example G.11) (0.503 g, 0.7 mmol), commercially available 5-bromo-pyridine-3-sulfonic acid amide (0.183 g, 0.77 mmol), tetrakis(triphenylphosphine)palladium (0.040 g, 0.030 mmol) in toluene (5 mL) was heated under reflux conditions for 18 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 (258 mg, 72%). MS (ISP) 514.2 [(M+H)+]; mp>250° C.
