Procedure

To a solution of N-[6-(4-amino-2-fluorophenoxy)imidazo[1,2-a]pyridin-2-yl]cyclopropanecarboxamide (100 mg, 0.306 mmol) and 1-(4-fluorophenyl)-6-methyl-2-oxo-1,2-dihydropyridine-3-carboxylic acid (90.8 mg, 0.367 mmol) in N,N-dimethylformamide (1.0 mL) were added HATU (151 mg, 0.397 mmol) and N,N-diisopropylethylamine (105 μL, 0.612 mmol), and the mixture was stirred at room temperature for 20 hr. Ethyl acetate and saturated aqueous sodium hydrogen carbonate solution were added to the reaction mixture, and the mixture was extracted 3 times with ethyl acetate. The combined organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and filtered, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate) to give a white solid. The obtained white solid was washed with ethyl acetate to give the title compound (131 mg, 77%) as a white solid.
