Procedure

A solution of methylamine in ethanol (33%, 75 ml.) was added to a solution of N-cyano-N'-[2-((5-methyl-4-imidazolyl)methylthio)ethyl]-S-methylisothiourea (10.1 g.) in ethanol (30 ml.). The reaction mixture was set aside at room temperature for 2.5 hours. Following concentration under reduced pressure, the residue was recrystallized twice from isopropyl alcohol/petroleum ether, affording N-cyano-N'-methyl-N"-[2-((5-methyl-4-imidazolyl)methylthio)ethyl]guanidine, m.p. 141°-143°.
