Reaction Steps

A suspension of (1E)-N′-(aminocarbonothioyl)-N,N-dimethylethanimidamide (47.8 g, 0.33 mole) in methyl iodide (150 mL) and THF (350 mL) was stirred for 18 h at room temperature. The mixture was evaporated under reduced pressure. After addition of 5% MeOH and diethyl ether, the compound precipitated and was collected by filtration affording (1E)-N′-[amino(methylthio)methyl]-N,N-dimethylethanimidamide hydrogen iodide salt (91.0 g, 96% yield).
