METHOD FOR PREPARING DIAMINOMALEONITRILE
A method for manufacturing diaminomaleonitrile, wherein the method includes at least one step during which a cyanohydrin ketone with formula RR′COHCN, R and R′, which are the same or different, being a straight or branched alkyl chain having 1 to 5 carbon atoms, reacts in order to provide diaminomaleonitrile. The reaction step may be carried out in the presence of a catalyst.

A facile regioselective synthesis of (5-amino-4-cyano-1H-imidazol-1-yl) benzoic acids
(Chemical Equation Presented) A simple and efficient method was developped for the synthesis of 3-(5-amino-4-cyano-1H-imidazol-1-yl)-4-substituted benzoic acids 3. These compounds were isolated by intramolecular cyclisation of the corresponding 3-{[(Z)-2-amino-1,2-dicyano-vinyl]amino}methyleneaminobenzoic acids in the presence of base.

Process for the purification of diaminomaleonitrile
Diaminomaleonitrile which is produced by the tetramerization of hydrogen cyanide is purified by heating a crude diaminomaleonitrile in an inert liquid or in an inert atmosphere at a temperature of 90° to 140° C, preferably 100° to 120° C, and then extracting pure diaminomaleonitrile having a purity of about 99% from said heated crude diaminomaleonitrile with a solvent.
