Versuchsvorschrift

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 piperazin-1-ol (21 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 (10 mL) and methanol (0.5 mL) 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 an orange solid.
