Reaction Steps
4-(2-Carboxyethyl)-2-formyl-3-methylpyrrole (90.6 mg), 88.6 mg 5-methoxycarbonyl-2-oxindole, and 75 μL piperidine in 2 mL of ethanol were heated at 95° C. for 5 hours. The reaction mixture was cooled and concentrated. The residue was suspended in 6 N aqueous hydrochloric acid. The precipitate was filtered, washed with water to pH 6 and dried in a vacuum oven to give 123 mg (69%) of the title compound as a yellow solid.
