Reaction Steps

A reaction mixture of 4-chloro-1,3-dihydro-pyrrolo[2,3-b]pyridin-2-one (85 mg, 0.5 mmol), 5-formyl-4-methyl-1H-pyrrole-2-carboxylic acid (2-morpholin-4-yl-ethyl)-amide (125 mg, 0.5 mmol), 0.1 mL of piperidine and 10 mL of ethanol was stirred at room temperature overnight. The yellow precipitate was filtered after cooled with an ice bath, washed with cold ethanol and dried to give 185 mg (92%) of 5-(4-chloro-2-oxo-1,2-dihydro-pyrrolo[2,3-b]pyridin-3-ylidenemethyl)-4-methyl-1H-pyrrole-2-carboxylic acid (2-morpholin-4-yl-ethyl)-amide.
