Nitropyrazoles 17.* Synthesis of 1-(3,5-dinitrophenyl)-4-methyl-3,5- dinitropyrazole and the study of its chemical transformations
A new one-step method for the synthesis of 4-methyl-3(5)-nitropyrazole by nitration of 4-methylpyrazole is developed. Arylation of 4-methyl-3(5)- nitropyrazole with 1,3,5-trinitrobenzene gives 1-(3,5-dinitrophenyl)-4-methyl-3- nitropyrazole, nitration of
