実験手順

To a solution of N-[6-(4-amino-2-fluorophenoxy)imidazo[1,2-a]pyridin-2-yl]cyclopropanecarboxamide (200 mg, 0.613 mmol) and 6-(4-fluorophenyl)-5-methylpyridine-2-carboxylic acid 1-oxide (212 mg, 0.858 mmol) in N,N-dimethylacetamide (2.0 mL) were added HATU (350 mg, 0.919 mmol) and N,N-diisopropylethylamine (160 μL, 0.919 mmol), and the mixture was stirred at room temperature for 6 hr. Ethyl acetate/tetrahydrofuran was added and 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 obtained residue was recrystallized from tetrahydrofuran to give the title compound (109 mg, 32%) as a white solid.
