Reaction Steps
To (3S,4S)-tert-butyl 3-(3-(3-ethyl-1-((6-methylpyridin-2-yl)methyl)-1H-indazol-4-ylcarbamoyl)imidazo[1,2-a]pyridin-7-yloxy)-4-hydroxypyrrolidine-1-carboxylate (22 mg, 0.036 mmol) in DCM (1 mL) was added TFA (1 mL). The reaction mixture was stirred for one hour, and then concentrated under reduced pressure. Silica gel chromatography (DCM/MeOH/NH4OH 10:1:0.1) provided the desired product (10 mg). MS (ES+APCI) m/z=512 (M+H).
