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 (0.2 g, 0.4 mmol), HOBt (54 mg, 1 eq.), EDAC (77 mg, 1 eq.) in DMF (1.5 mL) was stirred at rt for 10 mins. To the mixture was added (R)-1-(R)-1-pyrrolidin-2-ylmethyl-pyrrolidin-3-ol (0.2 g, 3 eq.). After stirring at rt for over the weekend, the precipitate was collected by vacuum filtration, washed with water, sodium bicarbonate and water, and then dried. The solid was purified on a silica gel column to give 159 mg (61%) of the titled compound.
