A new short and reasonably efficient synthesis of N-(2-ethylhexyl)-2,7-diiodocarbazole is presented. 4,4′-Diiodobiphenyl was nitrated and the resulting 4,4′-diiodo-2-nitrobiphenyl was converted via Freeman's modification of the Cadogan ring closure into 2,7-diiodocarbazole, which was then alkylated in the final step. The synthesis represents a significant simplification of the reported five-step procedure.
