| titleOfInvention | PROCESS FOR THE PREPARATION OF HETEROCYCLIC CARBONITRILES |
| abstract | Goal d. Erfindg. is it a procedure for d. To produce 2-amino-5-aryl-7-oxo-1,7-dihydro-pyrazolo & 1,5-a! -Pyridine-3,6-dicarbonitriles.The heterocyclic carbonitriles of the general formula II in which R is a optionally halogen-, alkyl- or alkoxy-substituted phenyl radical, can be prepared by reacting the substituted penta-1,4-diene-1,1,5,5-tetracarbonitrileeder the general formula I in which R has the above meaning, be prepared with hydrazine hydrate. These heterocyclic carbonitriles can be used as organic intermediates for further syntheses. They are particularly suitable for the preparation of novel heterocyclic compounds. |
