To N-(3-ethyl-1-((6-hydroxypyridin-2-yl)methyl)-1H-indazol-4-yl)imidazo[1,2-a]pyridine-carboxamide (11 mg, 0.027 mmol; prepared as in Example 17, Step A) in DMF (2 mL) was added K2CO3 (7.4 mg, 0.053 mmol) and iodomethane (19 mg, 0.13 mmol). The reaction mixture was stirred for one hour and concentrated under reduced pressure to remove DMF. Silica gel chromatography (DCM/MeOH 10:1) provided the desired product (3 mg). MS (ES+APCI) m/z=427 (M+H).
