Separately adding 6-brome indolone (500 mg, 2.36 mmol), 6-bromoisatin (533 mg, 2.36 mmol of isatin), 15 mL glacial acetic acid and 0.1 mL HCl into a flask, heating and refluxing for 24 hours. Stop the reaction and cooling to room temperature, filtering to obtain a solid, and then washing the solid by water, ethanol, and ethyl acetate. Drying the final product in a vacuum drying box, get brown 6,6′-bidromo isoindigo, the yield was 95%.
