Procedure

A mixture of {5-[5-(2,6-dichloro-phenylmethanesulfonyl)-2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrol-3-yl}-acetic acid (225 mg, 0.43 mmol), cyclopropyl-(S)-1-pyrrolidin-2-ylmethyl-amine (91 mg, 0.64 mmol), HOBt (91 mg, 0.67 mmol), EDAC (130 mg, 0.68 mmol) and TEA (0.15 mL, 1.1 mmol) in DMF was stirred at rt for 48 hours. The reaction was concentrated, diluted with sodium bicarbonate and extracted with DCM. The combined DCM was dried, concentrated and purified on a silica gel column to give 211 mg (76%) of the titled compound.
