7-Fluoro-N-(1-((6-isopropylpyridin-2-yl)methyl)-3-methyl-1H-indazol-4-yl)imidazo[1,2-a]pyridine-3-carboxamide (0.250 g, 0.565 mmol), 2-morpholinoethanol (0.371 g, 2.82 mmol), and potassium t-butoxide were combined in t-BuOH in a reaction tube. The tube was sealed and heated to 95° C. for 16 hours. After cooling to ambient temperature, the mixture was diluted with water and extracted with EtOAc. The combined organic extracts were with 10% aqueous potassium carbonate, dried over sodium sulfate, and concentrated. The resulting crude product was triturated with ether to give 165 mg (53%) of N-(1-((6-isopropylpyridin-2-yl)methyl)-3-methyl-1H-indazol-4-yl)-7-(2-morpholinoethoxy)imidazo[1,2-a]pyridine-3-carboxamide as a tan solid. MS (APCI), positive scan, m/z=554.1 (M+H).
