실험 절차

A solution of 2-(3-aminopropyl)imidazole, prepared from its dihydrochloride (0.9 g) by means of an ion-exchange resin (OH-1), and S-methylthiouronium sulphate (1.26 g) in water (20 ml) is heated under reflux for 18 hours. The product, isolated in a manner similar to that described in Example 1, is recrystallized from aqueous ethanol yielding 3-(2-imidazolyl)propylguanidine sulphate monohydrate, m.p. 260°-262° C. (dec.).
