Product 1

HCID 13910894N-(pyrazinylmethyl)ethylenediamine

Procedure

Ethylenediamine is reacted with 2-chloromethyl-pyrazine by the procedure of Example 34 to give N-(2-pyrazinylmethyl)ethylenediamine. Heating this compound with S-methylisothiourea in water under reflux for 3 hours by the procedure of Example 1 gives 2-(2-pyrazinylmethylamino)ethylguanidine.
