A solution of N-cyano-N'-methyl-methylsulfinylformamidine (493 mg) and 2-(5-methylimidazol-4-ylmethylthio)ethylamine (684 mg) in CH3CN (20 ml) was stirred for 4 hrs. at room temperature. After concentration under a reduced pressure, the residue was subjected to chromatography on SiO2 [eluant: CH3CN-CH3OH (4:1)]. The product obtained was recrystallized from CH3CN to give N"-cyano-N-methyl-N'-[2-(5-methylimidazol-4-ylmethylthio)ethyl]guanidine (684 mg). Yield 79.7%, m.p. 136°-138° C.
