Reaction Steps

To a mixture of 2-[4-(3-fluoro-phenyl)-2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-5-methyl-1H-pyrrole-3-carboxylic acid (100 mg, 0.28 mmol), EDC (64 mg, 1.2 eq.), HOBt (45 mg, 1.2 eq.) in DMF (3 mL) was added TEA (0.098 mL) and (3R,5R)-5-cyclopropylaminomethyl-pyrrolidin-3-ol. The mixture was stirred at rt for overnight. After the usual work up, 65 mg of the titled compound was obtained as a yellow solid.
