실험 절차

A mixture of (2-Formyl-4,5,6,7-tetrahydro-1H-indol-3-yl)-propionic acid (5.4 g), 4.0 g of 5-chloro-4-methyl-2-oxindole and 2.7 g of piperidine in 25 mL of ethanol was refluxed for 4 hours. Addition of acetic acid (8 mL) resulted in the formation of a precipitate. The mixture was refluxed for 5 minutes and cooled to ambient temperature. The precipitate was collected by vacuum filtration and washed with 20 mL of ethanol. The solids were slurry-washed with 30 mL of refluxing ethanol, cooled, collected by vacuum filtration, washed with 30 mL of ethanol and vacuum dried to give 6.8 g (80%) of 3-[2-(5-Chloro-4-methyl-2-oxo-1,2-dihydroindol-3-ylidenemethyl)-4,5,6,7-tetrahydro-1H-indol-3-yl]-propionic acid as an orange solid.
