A mixture of 7-chloro-N-(3-cyclopropyl-1-((6-methylpyridin-2-yl)methyl)-1H-indazol-4-yl)imidazo[1,2-a]pyridine-3-carboxamide (1.0 g, 2.2 mmol; prepared as in Example 65, step C)), 2-(2-(vinyloxy)ethoxy)ethanol (1.2 g, 8.8 mmol) and potassium hydroxide (0.61 g, 11 mmol) was dissolved in DMSO (10 mL). The reaction mixture was heated at 95° C. for 20 hours. The mixture was cooled to ambient temperature, transferred into water (100 mL) and saturated aqueous NaCl (200 mL) and stirred at ambient temperature for 4 hours. The resulting solid was collected by vacuum filtration and dried under vacuum to give the product (0.90 g). MS (ES+APCI) m/z=552.9 (M+H).
