A solution of 2-[[[5-(dimethylamino)methyl-2-furanyl]methyl]thio]ethanamine dihydrochloride (2.8 g) and potassium cyanate (3.75 g) in water (50 ml) was heated on a steam bath for 8 hr. Excess solid sodium carbonate was added and organic material continually extracted with diethyl ether. The extracts were evaporated and the residue after column chromatography yielded N-[2-[[[5-(dimethylamino)methyl-2-furanyl]methyl]thio]ethyl]urea as a waxy solid (1.28 g). Analysis Found: C, 48.22; H, 7.50; N, 15.61. C11H19N3O2S.H2O requires: C, 48.00; H, 7.63; N, 15.27%.
