γ-Carbolines were obtained in a simple one-pot Fischer arting from N-acetyl-3-bromo-4-piperidone hydrobro-reaction starting from N-acetyl-3-bromo-4-piperidone hydrobromide and substituted arylhydrazine hydrochlorides in acidic media under microwave irradiation or by a thermal process. The optimization procedures are reported in detail, and the results from micro-wave processes are compared with conventional
