Reaction Steps

To N-[4-({2-[(cyclopropylcarbonyl)amino]imidazo[1,2-a]pyridin-6-yl}oxy)-3-fluorophenyl]-1-(4-fluorophenyl)-6-methyl-2-oxo-1,2-dihydropyridine-3-carboxamide (700 mg, 1.26 mmol) was added acetic acid (3.5 mL), and the mixture was heated to 60° C. Methylethylketone (2.1 mL) and water (3.5 mL) were added, and the mixture was cooled to room temperature and stirred at room temperature for 16 hr. The precipitate was collected by filtration and washed with water to give the title compound (512 mg, 66%) as white crystals.
