Reaction Steps

2-[(2-{[tert-butyl(dimethyl)silyl]oxy}ethyl)amino]-N-[5-(3,5-difluorobenzyl)-1H-indazol-3-yl]-4-(4-methylpiperazin-1-yl)benzamide (126 mg, 0.2 mmol) was dissolved in dry THF (3 mL) and 1M TBAF in THF (0.24 mL) was added at 0° C. The resulting solution was stirred overnight at room temperature. Reaction was quenched with water and extracted with ethyl acetate. Collected organic phases were dried over Na2SO4, filtered and evaporated to dryness. Residue was purified by column chromatography over silica gel (DCM/EtOH/NH3 5N in MeOH=85/15/1) affording 83 mg of title compound.
