Versuchsvorschrift
To a solution of 9-p-tolyl-9H-carbazole (0.82 g, 3.2 mmol) in dichloromethane (DCM)(30 mL) was added N-bromosuccinimide (NBS) at about 0° C. The whole was stirred at about 0° C. to about room temperature (RT) overnight. The resulting solution was purified by flash column (silica gel, hexanes to hexanes/dichloromethane 8:1). After removal of solvent, a white solid (Compound 13) was obtained (1.0 gram, in 93% yield).
