Reaction Steps

1-(8-Fluoroquinolin-4-yl)-3-(6-iodopyridin-2-yl)urea (250 mg, 0.582 mmol), 2-(3,6-dihydro-2H-pyran-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (187 mg, 0.873 mmol), sodium carbonate solution (2M, 1.31 mL, 2.62 mmol) and tetrakis(triphenylphosphine)-palladium(0) (68 mg, 0.058 mmol) were dissolved in 5 ml of DMF under an argon atmosphere and the mixture was stirred at 80° C., in a microwave oven, for one hour. After the solvent had been evaporated down to dryness, the resulting residue was treated with water and the mixture was then extracted with ethyl acetate. After the combined organic phases had been dried over sodium sulfate and the solvent had been filtered and evaporated down to dryness, the resulting residue was purified by column chromatography to give the title product (50 mg, 19%).
