Procedure

To 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 (100 mg, 0.19 mmol), HOBt (3 mg, 0.1 eq.), EDAC.HCl (44 mg, 1.2 eq.) and 4-(2-amino-ethyl)-piperazin-2-one (30 mg, 1.1 eq.) in DMF (2 mL) at rt was added TEA (0.067 mL, 2.5 eq.). After stirring at rt for 7 days, the reaction was concentrated, diluted with DCM and then mixed with solid sodium bicarbonate. After stirring at rt for 15 mins, the suspension was loaded onto a silica gel column to give the titled compound as a pale orange solid.
