反応手順
A mixture of 2-oxindole (133 mg), indole-2-carbaldehyde (174 mg) (prepared according to Synthetic Communications, 1993, 23, 3109) and piperidine (10 mg) in ethanol was held in a sealed tube at 95° C. for 4 hours. The mixture was cooled to room temperature. The solid was collected by vacuum filtration, washed with cold ethanol and dried in a vacuum oven to give 3-(1H-indol-2-ylmethylene)-1,3-dihydro-indol-2-one.
