To 3-(3-ethyl-1-((6-methylpyridin-2-yl)methyl)-1H-indazol-4-ylcarbamoyl)imidazo[1,2-a]pyridine-7-carboxylic acid (26 mg, 0.057 mmol; prepared as in Example 28, Step A) in DMF was added formohydrazide (6.9 mg, 0.11 mmol), N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (22 mg, 0.11 mmol), 1H-benzo[c/][1,2,3]triazol-1-ol hydrate (15 mg, 0.11 mmol) and triethylamine (17 mg, 0.17 mmol). The reaction mixture was stirred for 16 hours at ambient temperature, diluted with DCM (30 mL), washed with H2O, dried (Na2SO4) and concentrated under reduced pressure. The residue was triturated with Et2O (30 mL) to give the product (20 mg).
