Abstract
The present invention relates to a 2,3-diaminoacrylonitrile derivative or salts thereof, having the formula ##STR1## wherein R represents an alkyl group (which may be substituted by unsubstituted or substituted phenyl groups, halogen atoms, C.sub.1-6 alkoxycarbonyl groups, carboxy groups, C.sub.1-6 alkoxycarbonyl C.sub.1-6 alkylthio groups, hydroxy groups, mercapto groups, cycloalkyl groups or heterocyclic groups containing oxygen atoms); an alkenyl group; a cycloalkyl group; an aryl group (which may be substituted by halogen atoms, C.sub.1-6 alkyl groups, nitro-groups, unsubstituted or substituted phenyl or phenoxy groups or heterocyclic groups containing oxygen atoms or sulfur atoms). The 2,3-diaminoacrylonitrile derivative can be used as starting materials for the production of pharmaceutical and/or agricultural intermediates such as cyanoimidazoles, cyanopyrazines or other cyano-substituted heterocycles.
