Abstract
PURPOSE: To obtain the titled compound useful as an intermediate for an agricultural chemical, medicine, etc. in simple operations without fear of fire, corrosion, etc. safely, industrially and advantageously, by reacting diaminomaleonitrile with formic acid in water as a solvent.
CONSTITUTION: Diaminomaleonitrile is reacted with formic acid in water as a solvent at 140W160°C under pressure to give the titled compound. The molar ratio between the diaminomaleonitrile and the formic acid is preferably 1: 2W4. The amount of the water as the solvent is preferably 3W10 times that of the diaminomaleonitrile. The reaction time is 5W10hr.
