New Heterocyclisation Reactions of 5-Amino-3-(cyanomethyl)-1H-pyrazole-4-carbonitrile with Some 1,3-Dielectrophilic Agents
5-Amino-3-(cyanomethyl)-1H-pyrazole-4-carbonitrile enters into condensation reactions with β-diketones and dibenzalacetone to form 2-(cyanomethyl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile derivatives. The reaction with cyanoguanidine in an acid medium leads to the formation of 2,4-diamino-7-(cyanomet...
