実験手順

The reaction of N-methyl-N'-[3-((4-methyl-5-imidazolyl)methylthio)propyl]thiourea (5.9 g.) with lead cyanamide (17.5 g.) by a procedure similar to that described in Example 3(b) afforded N-cyano-N'-methyl-N"-[3-((4-methyl-5-imidazolyl)methylthio)propyl]guanidine (0.91 g.), m.p. 156°-158°, following chromatography on silica gel with successive elution by chloroformethyl acetate (1:1), ethyl acetate and ethyl acetate isopropyl alcohol (5:1) and final recrystallisation from isopropyl alcohol-ether.
