Conditions

Temperature: 80 °C

Procedure

To a mixture of 6-bromo-2-(2-ethylsulfanylphenyl)-3-methyl-3H-imidazo[4,5-b]pyridine (350 mg) and 1,4-dioxane (5 ml), 3-fluorophenylboronic acid (150 mg), sodium carbonate (320 mg), and dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium(II) (22 mg) were sequentially added. The mixture was heated to 80° C. and stirred with heating for 8 hours. Into the mixture cooled to room temperature, water was poured, and extracted with ethyl acetate. 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 240 mg of 2-(2-ethylsulfanylphenyl)-6-(3-fluorophenyl)-3-methyl-3H-imidazo[4,5-b]pyridine (hereinafter referred to as Present Compound 61).
