Participants

Reaction Steps

A mixture of 5-[5-(2,6-dichloro-phenylmethanesulfonyl)-2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (250 mg, 0.5 mmol), HOBt (81 mg, 1.2 eq.), EDC (115 mg, 1.2 eq.), TEA (0.17 mL, 2.5 eq.) and (2R,3S)-2-cyclopropylaminomethyl-pyrrolidin-3-ol (312 mg, 4 eq.) in DMF (10 mL) was stirred at rt for overnight. The reaction was concentrated, washed with water, sodium bicarbonate and brine, dried and concentrated. The residue was purified on a silica gel column to give 100 mg of the titled compound as a yellow solid.
