Procedure
2-[[[5-(Dimethylamino)methyl-2-furanyl]methyl]thio]ethanamine (2.14 g) and isopropylisocyanate (0.89 g) were dissolved in acetonitrile and allowed to stand overnight. Solvents were removed and the residue recrystallised from methanol:ether to give N-[2-[[[5-(dimethylamino)methyl-2-furanyl]methyl]thio]ethyl-N'-(1-methylethyl)urea as crystals m.p. 65°-67° (2.8 g).
