Procedure

Aqueous sodium hydroxide (3.60 g, 0.9 mol) was added to a stirred ethanolic solution of 5-methyl-4-mercaptomethylimidazole hydrochloride (5.92 g, 0.03 mol) and N-cyano-N'-methyl-N"-(2-mercaptoethyl)guanidine (5.74 g, 0.0363 mol). The solution was cooled to 0° and a saturated ethanolic solution of iodine was added until the iodine color remained. The solvent was removed under reduced pressure to yield an oil which was purified using preparative high pressure liquid chromatography (silica gel; 13% methanol in ethyl acetate). The glassy product obtained was triturated with acetonitrile to yield N-cyano-N'-methyl-N"-[2-(5-methyl-4-imidazolylmethyldithio)ethyl]guanidine, m.p. 137°-142°; Ms m/e 284.
