Abstract
A preparative method of synthesis of 3-nitro-4-cyanopyrazole (1) from the available 3-amino-4-cyanopyrazole was developed. Chemical conversi ons of 1 were studied, and 3-nitro-4-R-pyrazoles (R = CO2H, CONH2, NHC O2Me, NH2, Br, NO2), as well as 3,5-dinitro-4-methoxycarbonylaminopyra zole were obtained starting from 1.
