Synthesis of 2-R-4,6-dinitro-2h-indazoles from 2,4,6-trinitrotoluene

An efficient synthesis of 2-R-4,6-dinitro-2H-indazoles (R = aryl or substituted amine) from 2,4,6-trinitrotoluene was elaborated. The proposed method includes formation of C-(2,4,6-trinitrophenyl)-N-R-azomethines 1 (a-g) from TNT or the product of its transformation 2,4,6-trinitrobenzaldehyde (TNBA) with the further regiospecific substitution of the ortho-nitro group in 1 (a-g) by the azido group under the action of NAN3. Thermolysis of the azides 2 (a-g) gives previously unknown 2-R-4,6-dinitro-2H-indazoles 3 (a-g) in high yields.
