Reaction equation
[S:1]1[CH:5]=[CH:4][N:3]=[C:2]1[CH2:6][NH:7][CH2:8][CH2:9][NH2:10].[CH2:11]([N:13]=[C:14]=[S:15])[CH3:12]>>[CH2:11]([NH:13][C:14]([NH:10][CH2:9][CH2:8][NH:7][CH2:6][C:2]1[S:1][CH:5]=[CH:4][N:3]=1)=[S:15])[CH3:12]Participants

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