Procedure

A mixture of N-[6-(4-amino-2-fluorophenoxy)imidazo[1,2-a]pyridin-2-yl]cyclopropanecarboxamide (150 mg, 0.459 mmol), 1-(2-chloro-4-fluorophenyl)-6-methyl-2-oxo-1,2-dihydropyridine-3-carboxylic acid (168 mg, 0.597 mmol), HATU (262 mg, 0.689 mmol), N,N-diisopropylethylamine (160 μL, 0.919 mmol) and N,N-dimethylformamide (3 mL) was stirred at room temperature for 18 hr. After dilution with ethyl acetate, the mixture was washed with saturated aqueous sodium hydrogen carbonate solution and saturated brine, dried over anhydrous magnesium sulfate and filtered. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (NH silica gel, 30 g, ethyl acetate/hexane=2/98→100/0), silica gel column chromatography (30 g, ethyl acetate/hexane=0/100→100/0) and preparative HPLC (acetonitrile/water=40/60→50/50, containing 0.1% trifluoroacetic acid) to give the title compound (101 mg, 37%) as a white solid.
