The Reactions of Hydroloide of 2-Amino-1-Substituted Guanidine Derivatives with Aromatic Isothiocyanates

摘要

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