Reaction Steps

To a solution of 3-tributylstannyl-5H,6H,12H,13H-indeno[2,3-a]pyrrolo[3,4-c]carbazole-7(7H)one (Step-1) (16 mg, 0.026 mmol) in dry CH2Cl2 (4 mL) was added a solution of I2 (8 mg, 2 mL CH2Cl2) dropwise. The mixture was stirred at ambient temperature 2 h., then a solution of 10% NaHSO3 was added. After stirring for 10 min. the mixture was filtered. The solid was collected and washed with water, CH2Cl2 and dried under vacuum (100° C., 6 h) to give 6 mg (53%) of Compound I-40, 1H NMR (DMSO-d6, 300 MHz) d 4.29 (s, 2H), 4.96 (s, 2H), 7.33-7.50 (m, 3H), 7.66-7.79 (m, 2H), 8.29 (s, 1H), 8.62 (s, 1H), 8.42 (d, 1H), 12.08 (s, 1H). MS (m/e)=437 (m+1)+.
