A mixture of 2-[[[5-(methylamino)methyl-2-furanyl]methyl]thio]ethanamine (2.0 g) and N-cyano-N'-methylcarbamimidothioic acid, methyl ester (1.25 g) was heated on a steam bath for 6.5 hr. Vacuum was applied at regular intervals to remove methanethiol. The crude product was purified by column chromatography Rf 0.65 (silica/methanol:ammonia 79:1) to give N-cyano-N'-[2-[[[5-(methylamino)methyl-2-furanyl]methyl]thio]ethyl]-N"-methylguanidine (1.05 g) m.p. 81°-85°.
