A mixture of the indolone (1.04 g, 4.2 mmol) and hydrazine monohydrate (1.12 mL, 22.4 mmol) in diethylene glycol (20 mL) was stirred at 80 °C for 1 h and then reflfluxed for 1 h. The resulting mixture was cooled to room temperature, treated with a solution of KOH (1.2 g, 21.4 mmol) in water (5 mL), and reflfluxed for 2 h. The resulting mixture was poured into water (100 mL), and the precipitate was fifiltered off, washed with water (5 × 50 mL), and dried to deliver 0.84 g (86%) of the indole as a greenish solid.
