実験手順
A mixture of 4 -methyl-5-((2-aminoethyl)thiomethyl)imidazole (5.1 g.) and methyl isocyanate (2.0 g.) in acetonitrile was heated for 18 hours in a pressure vessel at 100°. After cooling, the solid obtained was collected and recrystallised from isopropyl alcohol-acetonitrile to give N-methyl-N'-[2-((4-methyl-5-imidazolyl) methylthio)ethyl]urea (4.0 g.) m.p. 158°-159°.
