Versuchsvorschrift

The following reactants were combined in a 1-liter, round-bottom flask: 24.4 g (0.2 mole) diallylcyanamide, 13 g (0.2 mole) KCN and 500 ml methanol. The mixture was heated under reflux for 24 hours, then stripped in vacuo. The residue was dissolved in 250 ml H2O, which was subsequently extracted with three 200 ml portions of diethyl ether. The organic phases were combined, washed with 200 ml of H2O and dried with MgSO4. The solvent was evaporated to yield 20.7 g (67% yield) of N,N-diallyl-O-methyl isourea.
