Versuchsvorschrift
After suspending 4,5-dimethyl-4H-[1,2,4]triazol-3-ylamine (CAS 53132-83-5) (7.6 g) in acetonitrile (80 ml), a solution of phenyl isocyanatoformate (5.2 g) in acetonitrile (40 ml) was slowly added dropwise while heating to reflux. After heating to reflux for 6 hours, the reaction mixture was cooled on ice. The insoluble matter was collected by filtration to obtain the title compound (7.98 g).
