Reaction Steps

A mixture of 3-chloro-1,2,4-triazole (10.3 g., 0.1 m.) and 1,3-diaminopropane (7.4 g., 0.1 m.) in ethanol containing sodium ethoxide is allowed to stand overnight. The solvent is removed to give 3-(3-aminopropylamino)-1,2,4-triazole. This intermediate is reacted with methyl isothiocyanate to give N-methyl-N'-[3-(3-(1,2,4-triazolyl)amino)propyl]thiourea.
