α-Furoin (19.2 g; 0.1 mole) was reacted with 11.5 g (0.15 mole) ammonium thiocyanate in ethanol heated at reflux to afford 11.4 g of 4,5-bis-(2-furyl)-1H-2-imidazolethiol. An analytical sample was prepared by chromatography on alumina with ethanol and recrystallization from nitromethane, m.p. 279°-380° (dec.).
