Reaction Steps

The mixture of 4-(2-Amino-4-chloro-benzenesulfonylamino)-piperidine-1-carboxylic acid tert-butyl ester (20 mg, 0.051 mmol), rac-3-bromo-6-chloro-3-(3-chloro-benzyl)-1,3-dihydro-indol-2-one (30 mg, 0.081 mmol) and K2CO3 (30 mg, 0.22 mmol) in DCM (1 mL) was stirred at room temperature overnight. The mixture was purified by column chromatography to give 22 mg rac-4-{4-Chloro-2-[6-chloro-3-(3-chloro-benzyl)-2-oxo-2,3-dihydro-1H-indol-3-ylamino]-benzenesulfonylamino}-piperidine-1-carboxylic acid tert-butyl ester.
