A solution of 2-(4-dimethylaminomethyl-2-pyridylmethylthio)ethylamine (1 g) in ethanol (10 ml) was added over 10 minutes to a solution of dimethylcyanodithioimidocarbonate (0.71 g) in ethanol (15 ml). The solution was stirred for 30 minutes, evaporated to dryness and the residue purified by elution from a column of silica gel with 7.5% methanol/chloroform to yield N-cyano-S-methyl-N'-[2-(4-dimethylaminomethyl-2-pyridylmethylthio)ethyl]isothiourea (0.97 g) as a clear oil.
