Abstract

In the reaction of hydroiodide of methyl ester of S-methylthio- semicarbazide with primary amines hydroiodides of 2-amino-1-substitutedguanidine were obtained (1). These compounds were then converted to respective 3-arylamino-4-substituted Δ2-1,2,4-triazoline-5-thione and 3-benzylamino-4-substituted Δ2-1,2,4-triazoline-5-thione (2) in the reactions with isothiocyanates.
