실험 절차

2-Oxindole (3 g) was suspended in 1,2-dichloroethane and 3.2 mL of acetyl chloride slowly added. The resulting suspension was stirred at 50° C. for 5 hours, cooled, and poured into water. The resulting precipitate was collected by vacuum filtration, washed copiously with water and dried under vacuum to give 2.9 g (73% yield) of 5-acetyl-2-oxindole as a brown solid.
