반응 단계
A solution of 4-methyl-5-((2-aminoethyl)thiomethyl)imidazole (19.0 g.) and S-methylisothiourea sulphate (15.1 g.) in water (100 ml.) was heated under reflux for 3 hours. Concentration, acidification with sulphuric acid and dilution with ethanol afforded 2-[(4-methyl-5-imidazolyl)methylthio)ethyl]guanidine sulphate (13.0 g.) m.p. 230°-235° (from aqueous methanol).
