Abstract
A new approach to the synthesis of 3,5-dimethyl-N-nitro-1H-pyrazole-1-carboxamidine was developed based on condensing 1-amino-2-nitroguanidine with pentane-2,4-dione under alkaline catalysis. The known method of its preparation in the presence of acetic acid was improved. The structure of 3,5-dimethyl-N-nitro-1H-pyrazole-1-carboxamidine was characterized by NMR, IR spectroscopy and X-ray diffraction analysis.
