실험 절차

A stirred mixture of 2-(4-tributylstannanyl-imidazol-1-yl)-4-trifluoromethyl-6-(4-trifluoromethyl-phenyl)-pyridine (Example G.11) (0.718 g, 1.0 mmol), commercially available 3-bromophenylmethyl sulfone (259 mg, 1.1 mmol), tetrakis(triphenyl-phosphine)palladium (0.058 g, 0.050 mmol) in toluene (5 mL) was heated under reflux conditions for 18 h. Cooled to rt, some precipitate occurred, diluted with toluene (˜5 mL), placed in freezer for 30 min, added heptane (total volume: 25 mL), filtered the precipitate off, washed with toluene/heptane (ca. 1:1, 3×10 mL), purified by silica gel column chromatography with heptane/ethyl acetate followed by trituration with diethyl ether/heptane to give the title compound as a white solid (0.150 g, 29%). MS (ISP) 512.3 [(M+H)+].
