N-bromobutanimide → 3-bromo-9-(dibenzo[b,d]thiophen-4-yl)-9H-carbazole

Participants

Reaction Steps

N-bromosuccinimide (0.31 g, 1.74 mmol) in 5 mL DMF was added slowly to 9-(dibenzo[b,d]thiophen-4-yl)-9H-carbazole (0.6 g, 1.72 mmol) in 50 mL of DCM at 0° C. The reaction was allowed to warm to room temp and stirred overnight. The reaction mixture was extracted with DCM and dried over MgSO4 and the solvent was evaporated. The residue was purified by column chromatography using DCM:hexane (1:4, v/v) as the eluent to obtain 0.45 g of product.
