Reaction Steps

To a solution of rac-4-{4-Bromo-2-[6-chloro-3-(3-chloro-benzyl)-2-oxo-2,3-dihydro-1H-indol-3-ylamino]-benzoylamino}-piperidine-1-carboxylic acid tert-butyl ester (30 mg, 0.044 mmol) in DCM (2 mL) was added TFA (0.5 mL). The mixture was stirred for 3 h, concentrated. The residue was dissolved in DCM, the resulting solution was washed with Na2CO3 solution, dried with Na2SO4, concentrated to give 22 mg rac-4-Bromo-2-[6-chloro-3-(3-chloro-benzyl)-2-oxo-2,3-dihydro-1H-indol-3-ylamino]-N-piperidin-4-yl-benzamide.
