Reaction Steps

Reacting N-(2-pyrazinylmethyl)ethylenediamine with ethyl isothiocyanate by the procedure of Example 3 and chromatographing gives N-ethyl-N'-[2-(2-pyrazinylmethylamino)ethyl]thiourea. Reacting this thiourea with lead cyanamide by the procedure of Example 3 gives N-cyano-N'-ethyl-N"-[2-(2-pyrazinylmethylamino)ethyl]-guanidine.
