Versuchsvorschrift

To a mixture of 6-amino-2-oxindole (1 g) and acetyl chloride (0.79 g) in 10 ml of dichloromethane at 0° C. was added triethylamine (1 g). The mixture was brought to room temperature and stirred for 4 hours protected from atmospheric moisture with a dry-tube. The solvent was then evaporated and the residue was recrystallized from methanol to give 0.98 g (77%) of 6-acetylamino-2-oxindole as a beige solid.
