The rapid synthesis of 3-bromocarbazole-N-acetic acid was performed using microwave irradiation. Under the optimal conditions the yield was 85.6%. The crystal structure showed that the carboxylic groups form bifurcated hydrogen bonds and the hydroxyl oxygen atoms serve as proton donors and also acceptor. Each carboxylic group was involved in four hydrogen bonds. The packing of crystal was dominated by links of these hydrogen bonds.
