According to literature reports 1, 2 , a 100 mL flask containing a stirring bar was charged with 2-aminobenzamide (10 mmol, 1.0 equiv.), ketone (10.5 mmol, 1.05 equiv.), iodine and DMF (0.67 M). The reaction mixture was stirred at 80 °C for 12-36 hours. The reaction was cooled to 20 °C and water (50 mL) was added to the reaction generating precipitate that was collected as crude product by suction filtration. The crude material was washed with water and purified by recrystallization (EtOH) to give targeted product.
