実験手順
A mixture of 6-bromo-2-(2-ethylsulfanylphenyl)-3-methyl-3H-imidazo[4,5-b]pyridine (500 mg), NMP (24 ml), xylene (10 ml), copper iodide (1.1 g), and sodium pentafluoropropionate (1.1 g) was heated to 170° C., and stirred with heating for 3 days. Into the reaction mixture cooled to room temperature, saturated aqueous sodium hydrogen carbonate solution was poured, and extracted with tert-butyl methyl ether. The organic layer was dried over sodium sulfate, and concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography to give 43 mg of 2-(2-ethylsulfanylphenyl)-3-methyl-6-pentafluoroethyl-3H-imidazo[4,5-b]pyridine hereinafter referred to as Present Compound 55).
