5-(2,6-Dichloro-phenylmethanesulfonyl)-1,3-dihydro-indol-2-one was condensed with 5-formyl-2,4-dimethyl-1H-pyrrole-3-carboxylic acid using the general condensation method to give 5-[5-(2,6-dichloro-phenylmethanesulfonyl)-2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrole-3-carboxylic acid. This was then coupled with cyclopropyl-piperidin-4-yl-amine TFA salt (prepared as in lit. procedure by H. C. Hansen et al. Bioorg. Med. Chem. Lett. 10, 2000, 2435-2439.) using the general amidation procedure to give an orange solid.
