Versuchsvorschrift

17.5 g (0.10 mol) of 1-acetyl-2-indolinone are dissolved in 100 ml of conc. sulphuric acid and at −10° C. 8.8 g (0.11 mol) of ammonium nitrate are added batchwise and stirred for 15 minutes. The reaction is poured onto ice water, suction filtered and washed with water. The residue is distributed in ethyl acetate/water, the combined organic extracts are dried and concentrated by evaporation.
