To N3-(3-ethyl-1-((6-methylpyridin-2-yl)methyl)-1H-indazol-4-yl)-N7-(pyrrolidin-3-yl)imidazo[1,2-a]pyridine-3,7-dicarboxamide (5 mg, 0.0096 mmol; prepared as in Example 46) in DCM/MeOH (1 mL/1 mL) was added HCHO as a 35% aqueous solution (16 mg, 0.19 mmol) and NaBH(OAc)3 (10 mg, 0.048 mmol). The reaction mixture was stirred for one hour, concentrated under reduced pressure and the residue was purified by silica gel chromatography (DCM/MeOH/NH4OH 10:1:0.1) to provide the final product (4 mg). MS (ES+APCI) m/z=537 (M+H).
