tert-Butyl 6-(2-(3-(1-((6-isopropylpyridin-2-yl)methyl)-3-methyl-1H-indazol-4-ylcarbamoyl)imidazo[1,2-a]pyridin-7-yloxy)ethyl)-2,6-diazaspiro[3.3]heptane-2-carboxylate (0.075 g, 0.113 mmol) was dissolved in 2 mL of 1:1 DCM/MeOH and 4M HCl/dioxane (0.282 mL, 1.13 mmol) was added. The mixture was stirred at ambient temperature for 4 hours, then concentrated under reduced pressure. The resulting residue was triturated with DCM and the solids were collected by filtration to give 57 mgs (75%) of the title compound. MS (APCI), positive scan, m/z=567.1 (M+H).
