Procedure

To a solution of N-[6-(4-amino-2-fluorophenoxy)imidazo[1,2-a]pyridin-2-yl]cyclopropanecarboxamide (90 mg, 0.276 mmol) and 1-(4-fluorophenyl)-2-oxo-6-(trifluoromethyl)-1,2-dihydropyridine-3-carboxylic acid (100 mg, 0.331 mmol) in N,N-dimethylformamide (2 mL) were added N,N-diisopropylethylamine (95 μL, 0.552 mmol) and HATU (126 mg, 0.331 mmol), and the mixture was stirred at room temperature for 6 hr. Ethyl acetate, tetrahydrofuran and saturated aqueous sodium hydrogen carbonate solution were added to the reaction mixture, and the mixture was extracted 3 times with ethyl acetate. The 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 washed with ethyl acetate and collected by filtration. The obtained slightly yellow solid was suspended in ethanol (3 mL), and the mixture was stirred at 70° C. for 17 hr. The suspension was collected by filtration and washed with ethanol to give the title compound (32.7 mg, 19%) as a slightly yellow solid.
