Use of the graebe-ullmann reaction in the synthesis of 8-methyl-γ- carboline and isomeric aromatic aza-γ-carbolines

Two variants of the Graebe-Ullmann reaction were used to obtain 8-methyl-5H-pyrido[4,3-b]indole (8-methyl-γ-carboline) and the conditions for this reaction were optimized. The feasibility of using this method was studied for the synthesis of a series of isomeric aromatic aza-γ- carbolines from the corresponding 1-(pyridyl)-1H-1,2,3-triazolo[4,5-c]pyridines under thermal and microwave irradiation conditions.
