Reaction Steps

A mixture of 4-[2-({5-[5-(2,6-dichloro-phenylmethanesulfonyl)-2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrole-3-carbonyl}-amino)-ethyl]-piperazine-1-carboxylic acid tert-butyl ester (370 mg, 0.52 mmol) and TFA (3 mL) in DCM (20 mL) was stirred at rt for overnight. The reaction was concentrated and purified to give 5-[5-(2,6-dichloro-phenylmethanesulfonyl)-2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (2-piperazin-1-yl-ethyl)-amide.
